Question

The following two isomers of C3H7NO exist in equilibrium with each other in solution:

If Kc = 0.57 at 25C and the initial concentration of the reactant is 0.50 M and the product is 0.70 M, what are the concentrations at equilibrium?
A) [reactant] = 0.43 M and [product] = 0.24 M
B) [reactant] = 0.67 M and [product] = 0.38 M
C) [reactant] = 0.76 M and [product] = 0.44 M
D) [reactant] = 0.82 M and [product] = 0.47 M
