Question

For the reaction C2H4(g)+H2(g)⇆C2H6(g), which of the following is true at 27°C?
A)Kp is greater than Kc.
B)Kp is smaller than Kc.
C)Kp=Kc.
D)Can't be predicted.
Please explain.

Answer 1

∆n = -1
kp= kc{RT}^-1
kp=kc/RT

it mean that when you divide kc to RT then it will be equal to kp
so kc>>kp

i hope this will help you
