Question

In the equilibrium constant expression for the reaction below what is the correct exponent for n2o4 ? n2o4 (g) 2no2 (g) 2 4 1 6

Answer 1

Answer: 1

Explanation:

Equilibrium constant is the ratio of product of concentration of products to the product of the concentration of reactants each term raised to their stochiometric coefficient.

`N_2O_4\rightleftharpoons 2NO_2`

`K=([NO_2]^2)/([N_2O_4]^1)`

Thus the exponent for the concentration of
`N_2O_4` is 1.

Answer 2

The balanced equation:
N₂O₄(g) ↔ 2 NO₂(g)
From the equation we can write equilibrium constant expression as follows:
Keq = [NO₂]² / [N₂O₄]
So the correct exponent for N₂O₄ equal 1
The correct answer is one
