Question

For the given chemical equation 2X(g) + Y(g) $\rightleftharpoons$2Z(g) + 8 kcal, which combination of pressure and temperature gives the highest yield of ‘Z’ at equilibrium?

Options

A.1000 atm and 500oC
B.500 atm and 500oC
C.500 atm and 100oC
D.1000 atm and 100oC

Solution

For forward reaction (exothermic), temperature should be low. As mole of gas is decreasing, the pressure should be high.
