The formation of ammonia from its constituent elements is an exothermic reaction. The effect of increase temperature on the reaction equilibrium is

Options

  1. AThe rate of the forward reaction becomes zero
  2. BNo effect of temperature.
  3. CForward reaction is favored
  4. DBackward reaction is favored

Correct answer

D. Backward reaction is favored

Step-by-step solution

Consider the reaction of formation of ammonia from nitrogen and hydrogen by Haber's process: N 2 g + 3 H 2 g ⇌               2 NH 3 g ;   ∆ H = - 92 . 4   kJ The forward reaction is exothermic while, the reverse reaction is endothermic. If the temperature of the system in equilibrium in increased, according to Le Chatelier's principle, the system tries to decrease the temperature by absorbing heat. So, an increase in temperature favours the endothermi
