`K_p` for the reaction :
`N_2O_4(g) hArr 2NO_2(g)` is 0.157 atm at `27^@C` and 1 atm pressure . Calculate `K_c` for the reaction.

Text Solution

Verified by Experts

The correct Answer is:
`6.37 xx 10^(-3) mol L^(-1)`
`Delta n = n_(p) - n_(r) = 2 - 1 = 1`,
`K_(c) = K_(p)//(RT)^(Delta n) = (0.157 " atm)//(0.0821 L "atm" K^(-1) mol^(-1) xx 300 K)^(1) = 6.37 xx 10^(-3) mol L^(-1)`.
