###### Problem Details

Consider this system at equilibrium.

A (aq) $↔$ B (aq) ΔH - 450 KJ/mol

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

a) Q > K because Q increased

b) Q > K because K decreased

c) Q < K bc Q decreased

d) Q < K bc K increased

e) Q = K bc neither changed

How will the system respond to a temperature increase?

a) shift left

b) shift right

c) no change
