Question

The correct relation between Kp and Kc for the given reaction is:
H2(g)+l1(g)2Hl(g)
  1. KpRT=Kc
  2. Kp=Kc(RT)2
  3. Kp=Kc(RT)2
  4. Kp=Kc

A
Kp=Kc
B
KpRT=Kc
C
Kp=Kc(RT)2
D
Kp=Kc(RT)2
Solution
Verified by Toppr

The correct option is B Kp=Kc
Generally Kp=Kc(RT)Δn
Δn= no. of mole of products - no. of moles of reactants.
Here no. of product moles =2
no. of reactant moles =2
So Δn=22=0
Kp=Kc(RT)0=Kc
So for this reaction, Kp=Kc
