Question 31
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 \qquad \text{ethene} \end{array} C2​H6​(g)⇌C2​H4​(g)+H2​(g)ethaneethene​

State the maximum volume of ethene, in dm3\text{dm}^3dm3, that can be formed by the dehydrogenation of 250 dm3 of ethane.

(Assume all volumes of gases are measured under the same conditions of temperature and pressure.)
