Question

Consider the following reaction.
A(aq) (Two way arrows) 2B(aq)
Kc = 7.94*10^-6 at 500K
If a 2.70 M sample of A is heated to 500K what is the concentration of B at equilibrium?

Answer 1

Kc = ([x]^2)/A
7.94*10^-6 = ([x]^2)/2.70 M
2.1438*10^-5 = x^2
x = 4.630118789*10^-3
I hope this helps Janavi.
