The equation for the reaction in the figure below is : H 2 g + I 2 g + Heat ⇌ 2 HI g At instant 3 min, what change was imposed into the equilibrium?

Options

  1. APressure was increased
  2. BTemperature was increased
  3. CVolume of system decreased
  4. DCatalyst added to reaction mixture

Correct answer

B. Temperature was increased

Step-by-step solution

Temp. increase favours endothermic reaction in forward direction i.e. [HI] increased [I 2 ], [H 2 ] decreased Increase in pressure has no effect.
