The value of K _ C for the reaction, 2 ~A B + C is 2 10⁻³ . At a given time, the composition of reaction mixture is [ A ]=[ B ]=[ C ]=3 10⁻⁴ M . In which direction, the reaction will proceed?

Step-by-step solution

For the reaction, the reaction quotient Q _ C is given by Q _ C =[ B ][ C ] /[ A ]^2 Given that, [ A ]=[ B ]=[ C ]=3 10⁻⁴ M Then, Q _ C = (3 10⁻⁴ ) (3 10⁻⁴ ) (3 10⁻⁴ )^2 =1 As, Q _ C K _ C , so the reaction will proceed in the reverse direction.
