Question
For the isomerization equilibrium A(g) <=> B(g) the equilibrium constant Kc = 4.0 at a certain temperature. Starting with [A] = 1.0 M and [B] = 0, calculate the equilibrium concentration of B (in mol L^-1). Give the answer rounded to three decimal places.
✓ Verified answer: 0.8checked by our engine — not a guess
Step-by-step solution
Let y M of A convert to B. At equilibrium [A] = 1 - y, [B] = y. Kc = [B]/[A] = y/(1-y) = 4. So y = 4 - 4y, 5y = 4, y = 0.8 M. Final answer: 0.8
