Challenge

In the contact process, sulfur dioxide and oxygen make sulfur trioxide for sulfuric acid:

2SO2(g)+O2(g)⇌2SO3(g)ΔH=−196 kJ2\mathrm{SO_2(g)} + \mathrm{O_2(g)} \rightleftharpoons 2\mathrm{SO_3(g)} \qquad \Delta H = -196\ \mathrm{kJ}

The plant raises the pressure in its converter. Which way does the equilibrium shift?
