Answer:
0.076M = [NOBr]
Step-by-step explanation:
For the reaction:
2NO + Br₂ ⇄ 2 NOBr
The equilibirum constant, K, is defined as:
(1)
Replacing the concentrations and the equilibrium value in (1):
![1.3x10^(-2) = ([NOBr]^2)/([0.89]^2[0.562])](https://img.qammunity.org/2021/formulas/chemistry/high-school/akzyzyelsoy2hqdbiezmnqsdinusnxdffg.png)
5.79x10⁻³ = [NOBr]²
0.076M = [NOBr]
I hope it helps!
