The equation for this gas-phase equilibrium reaction is:
C2H6(g)⇌C2H4(g)+H2(g)ethaneethene \begin{array}{c} \text{C}_2\text{H}_6(\text{g}) \rightleftharpoons \text{C}_2\text{H}_4(\text{g}) + \text{H}_2(\text{g}) \\ \text{ethane} \qquad \text{ethene} \end{array} C2H6(g)⇌C2H4(g)+H2(g)ethaneetheneThe forward reaction is endothermic.
A chemical manufacturer wants to produce large quantities of ethene economically.
Suggest, with explanations, the conditions of temperature, pressure, and the use of a catalyst that the manufacturer should choose to achieve an optimum balance between the rate of reaction and the yield of ethene.
