Answer 1: Question 4 0/1 pts Assume that an endothermic reaction is at equilibrium. The reaction is then cooled. Determine the effect that the stress will have on the reaction by choosing one of the following options: 1) shift to products 2) shift to reactants 3) no change. Answer with the appropriate number (i.e. 1 if it shifts to the products)

Explanation / Answer

Question 3: conjugate acid is essentially a protonated base. In the given reaction, HSO4- is the acid and H2O is the base, they react to give H3O+ and (SO4)2-. Hence the protanated base form is H3O+ which is thus the conjugated acid.

Question 4: Endothermic reaction means, the reaction requires heat to be taken up from the surroundings in order to form products. When the reaction is cooled, heat transfer ability from surroundings is inhibited as the surroundings have now lower temperature. Hence this will cause lesser product formation, or in other words, reaction will shift to reactants, ie, option 2.
