The reaction 3A(g)+B(g)⇌2C(g)\mathrm{3A(g) + B(g) \rightleftharpoons 2C(g)}3A(g)+B(g)⇌2C(g) is at equilibrium in a sealed container. The forward reaction is exothermic.
The temperature and the pressure of the mixture are then both decreased.
Explain how each change affects the position of equilibrium and whether the overall change in the amount of C\mathrm{C}C at equilibrium can be predicted.
