Question

13. The equilibrium constant for the reaction
N26) +0266)
2NO is 4 x 10-4 at 200 K. In presence
(g)
of a catalyst the equilibrium is attained 10 times faster.
Therefore, the equilibrium constant in presence of
catalyst at 200 K is
(a) 40 104
(b) 4 x 10-4
(c) 4 x 10-3
(d) Can't be calculated​

Answer 1

Answer

Correct option is

C

4×10

−4

Therefore the equilibrium constant in the presence of a catalyst at 2000 K is same as the equilibrium constant in the absence of catalyst at 2000 K. It is 4×10

−4

.

The presence of catalyst does not affect the value of the equilibrium constant. It only increases the rates of forward and reverse reaction to equal extent.
