For a reaction A s ⇌ B s + C g the set of all correct statements are a) K is independent of A . b) K is dependent on partial pressure of C at a given temperature. c) ΔH will be independent of temperature. d) ΔH is independent of the catalyst addition.

Options

  1. Aa,b,c,d
  2. Ba,b only
  3. Ca,b,d only
  4. Da,b,c only

Correct answer

C. a,b,d only

Step-by-step solution

Given reaction is A s ⇌ B s + C g Equilibrium constant for this reaction K C   =   C concentration of solid is considered as one during heterogenous equilibrium. So, as we can see K is independent of A . Similarly K P   =   P C So, K is dependent on partial pressure of C . Note: Although the value of equilibrium constant does not depend on concentration of reactants or products at a given temperature. Enthalpy change depends on temperature, but it is independent of catalyst used. So, state
