If the temperature is increased for following reaction, then it will go in: N2+3H2⇌ 2NH3 ∆H=-Ve
Correct answer: B. Reverse direction.
- A. Forward direction.
- B. Reverse direction.
- C. Remain constant.
- D. Cannot be predicted.
Explanation
For exothermic reaction: Yield ∝ 1/TemperatureIf temperature is increased, then yield of product become less. It means reaction move in reverse direction.

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
