Equilibria — practice question

Ethanol is produced by reacting ethene gas with steam in the presence of phosphoric(V) acid. $\text{C}_2\text{H}_4(\text{g}) + \text{H}_2\text{O}(\text{g}) \rightleftharpoons \text{C}_2\text{H}_5\text{OH}(\text{g}) \qquad \Delta H = -45\,\text{kJ mol}^{-1}$ This reaction is performed at $570\,\text{K}$ and $60\,\text{atm}$. What would happen if the reaction were carried out at the same temperature but under a pressure of $200\,\text{atm}$?
