Question

Give the example for gaseous reversible reaction for which kp=kc

Answer 1

H2+ I2 gives2 HI is the reversible reaction which is example for kp= kc

Answer 2

Answer: $H_2(g)+I_2(g)\rightarrow 2HI(g)$

Explanation:- 

$K_p=K_c\times (RT)^{\Delta n_g}$

where: $\Delta n_g$= number of moles of gaseous products - number of moles of gaseous reactants

R = gas constant

T= temperature

For reaction; $H_2(g)+I_2(g)\rightarrow 2HI(g)$

$\Delta n_g$= number of moles of gaseous products - number of moles of gaseous reactants= 2-2= 0

$K_p=K_c\times (RT)^0$

$K_p=K_c$              $(RT)^0=1$
