🤓 Based on our data, we think this question is relevant for Professor Reddie's class at UML.
Consider this system at equilibrium.
A(aq) ⇌ B(aq) ΔH = +550 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 because Q decreased
D) Q < K because K increased
E) Q = K because neither changed
How will the system respond to a temperature increase?
A) shift left
B) shift right
C) no change
We are being asked what would happen to the equilibrium constant (K) and the reaction quotient (Q) of the reaction at equilibrium when the temperature is increased.
To determine what would be the effect of the temperature in the equilibrium reaction, let’s first identify if the reaction is endothermic or exothermic.
• ΔH > 0
• the system or the reaction is absorbing heat or taking heat from the surrounding
