Consider this system at equilibrium.

A(aq) <==>B(aq)

Delta H= -550 kL/mol

What can be said about Q and K immediately after an increase in temperature?

AQ > K because Q increased
BQ > K because K decreased
CQ < K because Q decreased
DQ < K because K increased
EQ=K because neither changed

How will the system respond to a temperature increase?


1, shift left

2, shift right

3, no change

The given reaction is an exothermic reaction due to the negative amount of enthalpy. In this case, an increase in temperature favors the backward reaction which points to the creation of more products. The expression of K or Q is products over reactants concentration. When this happens, Q becomes smaller then. Hence answer is C and 1.
