Explanation / Answer

a) you are adding a reactant, so more product (SO2forms) FAlse b)   delH > 0,   so endothermic. Increasingtemperature favors the forward rection; increases concentration c) you are adding a product, reaction shifts to left; SO2 isconsumed.   TRUE d) increasing volume decreases pressure. But there are more molesof gas on the right side of the equation than on the left. Recallthat P = nRT/V. P can readjust if n increases. So moreproduct is formed. FALSE e) catalysts affects only kinetics. Not equilibrium. No change ANSWER is C) PM me if you need more help with this.
