Given reaction is `2X_((gas)) + Y_((gas))hArr2Z_((gas)) + 80` Kcal
Which combination of pressure and temperature gives the highest yield of Z at equilibrium ?

Answer

C

Explanation

The given reversible reaction, in the forward direction, is exothermic and proceeds with a decrease in volume of gaseous constituents. As such low temperature and high pressure will favour the forward process to give the highest yield of product i.e., Z.
