Q. In the given reaction, $2X(g) + Y(g) \rightleftharpoons 2Z(g) + 80\ kcal,$ Which combination of pressure and temperature will give the highest yield of Z at equilibrium?
A) 1000 atm and 200$℃$
B) 500 atm and 500$℃$
C) 1000 atm and 100$℃$
D) 500 atm and 100$℃$
Explanation
(c)
In this equation, volume is decreasing and the reaction is exothermic. So, for the highest yield of Z, pressure should be high and temperature should be low.
