The equation shows the reversible reaction between ethene and steam. $\text{C}_2\text{H}_4(g) + \text{H}_2\text{O}(g) \rightleftharpoons \text{C}_2\text{H}_5\text{OH}(g)$ \qquad $\Delta H$ is negative Which row gives the conditions that result in the highest yield of ethanol?
- Alow pressure, low temperature
- Blow pressure, high temperature
- Chigh pressure, low temperature
- Dhigh pressure, high temperature
