Kc for the reaction : N2(g) + O2(g) 2NO(g) is 4.0 x 10-6 at 400 K. Kp for the above reaction is

A

2.4 x 10-3

B

4.0 x 10-6

C

4 x 10-6 x (RT)2

D

None of these

Answer

4.0 x 10-6

Explanation

Solution

N2+O2\mathrm { N } _ { 2 } + \mathrm { O } _ { 2 }

for this reaction

Since

∴Kp=Kc\therefore \mathrm { K } _ { \mathrm { p } } = \mathrm { K } _ { \mathrm { c } }
