Question

For the reaction equilibrium 2nobr g) = 2no(0) b1,0) at equilibrium and p is total pressure, the ratio of is equal to to

Answer 1

Answer:

⇋2NO

(g)

+Br

2(g)

.

The partial pressure of bromine is

9

P

. The partial pressures of NOBr and NO will be

9

7P

and

9

2P

respectively.

The expression for the equilibrium constant will be K

p

=
