Ethene may be oxidised to produce epoxyethane, $\text{C}_2\text{H}_4\text{O}$. $\text{C}_2\text{H}_4(g) + \tfrac{1}{2}\text{O}_2(g) \rightleftharpoons \text{C}_2\text{H}_4\text{O}(g) \quad \Delta H^{\circ} = -107\,\text{kJ mol}^{-1}$ Which combination of conditions results in the highest equilibrium yield of epoxyethane?
- Ahigh pressure, $100\,^{\circ}\text{C}$
- Bhigh pressure, $200\,^{\circ}\text{C}$
- Clow pressure, $100\,^{\circ}\text{C}$
- Dlow pressure, $200\,^{\circ}\text{C}$
