Study the reaction.
A(s) + 2BC(aq) →AC2(aq) + B2(g)
ΔH = −92.0 kJ/mol
Which change would increase the rate of the forward reaction?
increasing the pressure
decreasing the temperature
adding more of A(s)
adding water
B?
I agree.
I don't know how you've been taught but I rewrite equations like this so I can see where the heat is involved. For this one I would rewrite the equation of
A(s) + 2BC(aq) →AC2(aq) + B2(g)
ΔH = −92.0 kJ/mol and then the rewrite as
A(s) + 2BC(aq) →AC2(aq) + B2(g) + heat
Then by LeChatelier's Principle, you know if you ADD heat the reaction shifts to the left or by cooling the reaction shifts to the the right.
