Question

The value of kc in the reaction : 2a=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

Answer 1

2a=b+c

Now value of K at r=t is equal to [B] [c]/[A]^{2}, this will equal to 1.

Then, Kc = 2*10^-3

The above mention observations show that reaction will proceed backward. The Kc is an equilibrium constant whose value depends upon reactants and finally delivered products. At the same time, only temperature is a factor that can change the value of Kc in a given reaction.
