QJEEM19Ch3953: JEE Main 2019 Chemistry - Class 11 JEEM19Ch3953 Solution: For the reaction, 2SO 2 (g) + O 2 (g) = 2SO 3 (g), Δ H = –57.2…

For the reaction,
2SO2(g) + O2(g) = 2SO3(g), ΔH = –57.2 kJ mol–1 and KC = 1.7 × 1016
Which of the following statement is incorrect ?

Multiple Choice Options

  • A The equilibrium will shift in forward direction as the pressure increase.
  • B The addition of inert gas at constant volume will be not affect the equilibrium constant.
  • C The equilibrium constant is large suggestive of reaction going to completion and so no catalyst is required.
  • D The equilibrium constant decreases as the temperature increase.

Step-by-Step Verified Solution

Equilibrium constant has no relation with catalyst.

Catalyst only affects the rate with which a reaction proceeds.

Here we use catalyst V2O5 to speed up the reaction.
