If a 1.60 M sample of A is heated to 500 K, what is the concentration of B at equilibrium?

A(aq)<---> 2B(aq)

Kc=9.63x10^-6

1 answer

..........A --> 2B
I.......1.60.....0
C........-x......2x
E......1.60-x....2x

Assuming Kc listed is at 500K, substitute the E line into Kc expression and solve for x and 1.60-x.
