The reverse reaction is an endothermic reaction. It is favored by increase in temperature. It is also favored when either some hydrogen is removed or some ethane is added. Because the equilibrium will shift to left so that more hydrogen is formed or more ethane is consumed.
All these will increase the equilibrium moles of ethylene.

For the gas phase reaction, C4H2+H2⇌C2H6(△H=−32.7 kcal) carried out in a vessel, the equilibrium moles of C2H4 can be increased by:increasing the temperaturedecreasing the temperatureremoving some H2adding some C2H6

For the gas phase reaction, $C_{4} H_{2} + H_{2} ⇌ C_{2} H_{6} (△ H = - 32.7 k c a l)$ carried out in a vessel, the equilibrium moles of $C_{2} H_{4}$ can be increased by:
increasing the temperature
decreasing the temperature
removing some $H_{2}$
adding some $C_{2} H_{6}$
