Homework Answers
Option D is correct, because value of equilibrium constant depends only on temperature and as the reaction is exothermic in nature so if we lower down the temperature reaction moves forward in direction and hence increases the value of equilibrium constant i.e., Kc.

t. For an exothermic reaction, the equilibrium constant, Kc, becomes smaller as the temperature increases and larger as the temperature decreases. u. The gas-phase equilibrium shown below is used to produce ammonia, NH3, for commercial applications. The NH3 yield can be increased by decreasing the temperature, increasing the pressure, and removing some NH; from the mixture. N2(g) + 3H2(g) - 2NH3() AH = -94 kJ. v. For the gas-phase equilibrium described above (see problemlu), an increase in...
