Correct Answer: C. simple majority system

Explanation

A first-past-the-post (FPTP and sometimes abbreviated to FPP) electoral system is one in which voters indicate on a ballot the candidate of their choice, and the candidate who receives the most votes wins. This is sometimes described as winner takes all. First-past-the-post voting is a plurality voting method. FPTP is a common, but not universal, feature of electoral systems with single-member electoral divisions, and is practiced in close to one third of countries. Notable examples include Canada, India, the United Kingdom, and the United States, as well as most of their current or former colonies and protectorates. Simple majority may refer to: Majority, a voting requirement of more than half of all ballots cast.

Correct Answer: B) Increase of concentration of CO

Explanation

In order to understand the factors that affect the equilibrium constant of a reaction, we need to learn about Le Chatelier's principle. Le Chatelier's principle states that if a dynamic equilibrium is disturbed by changing the conditions, the position of the equilibrium will shift to counteract the change.

In the given reaction CO\(_{(g)}\) + H\(_2\)O \(\iff\) CO\(_{2(g)}\) + H\(_{2(g)}\), let's discuss how each option affects the equilibrium:

Option A: Increase of temperature

Changing the temperature of a reaction can affect the position of the equilibrium, but it does not change the equilibrium constant. This is because the equilibrium constant is only dependent on temperature. So, an increase in temperature will shift the equilibrium position, but not change the equilibrium constant.

Option B: Increase of concentration of CO(Correct)

According to Le Chatelier's principle, increasing the concentration of reactants will shift the equilibrium position towards the products, but it will not change the equilibrium constant. The equilibrium constant is a ratio of the concentrations of the products to the reactants, so changing the concentration of one reactant does not change the overall constant value.

Option C: Removal of CO\(_2\) from the mixture

Removing a product from the reaction mixture will shift the equilibrium position towards the products, according to Le Chatelier's principle. However, this also does not change the equilibrium constant, as it is still a ratio of the concentrations of the products to the reactants.

Option D: Decrease of pressure

Decreasing the pressure of a reaction will cause the equilibrium to shift in the direction that has more moles of gas, in order to counteract the decrease in pressure. In this case, since both sides of the reaction have the same number of moles of gas, a decrease in pressure will not affect the equilibrium position or the equilibrium constant.

In conclusion, although some of the options can affect the position of the equilibrium, none of them will change the equilibrium constant of the given reaction. To learn more about this, please read the relevant sections of the recommended textbooks.

Correct Answer: C. A group of firms producing related goods

Explanation

An industry is a group of firms producing similar products and under separate administration or management.

Correct Answer: C. Indifferent to the world

Correct Answer: C) Many factors leads to change in demand but only change in price affect change in quantity demanded

Explanation

This question is asking about the difference between change in demand and change in quantity demanded. These two terms may sound similar, but they have different meanings. Change in demand refers to a shift in the entire demand curve, while change in quantity demanded refers to a movement along the demand curve.

Option A states that all factors affecting change in demand also affect change in quantity demanded except income. This is incorrect because changes in factors such as taste, price of substitutes or complements, and future expectations can cause a shift in demand, but won't necessarily affect the quantity demanded.

Option B says that all factors affecting change in demand are not affecting change in quantity demanded except income. This is also incorrect because changes in many factors can affect both demand and quantity demanded.

Option C is the correct answer. It says that many factors lead to a change in demand, but only a change in price affects the quantity demanded. This is because a change in price causes a movement along the demand curve, while a change in any other factor leads to a shift in the demand curve.

Option D is incorrect because changes in income can affect both demand and quantity demanded, while changes in other factors such as taste or the price of substitutes may only affect demand.

In summary, the correct answer is option C because a change in price is the only factor that affects quantity demanded, while changes in other factors lead to a shift in demand.
