1670J = mass ice x heat fusion.
The system shifts to undo what we've done. How can it do that? Obviously, if we decrease T the system will try to increase T. Which way will it shift to do that?
What mass of ice at 0°C can be melted by the addition of 1670 joules of heat?
When the temperature is decreased on the following system at equilibrium:
2 HCl(aq) + Mg(s) <--> MgCl2(aq) + H2(g) + heat
a. In order to restore equilibrium, the reaction shifts left, toward reactants
b.No change occurs
c. In order to restore equilibrium, the reaction shifts right, toward products
