Question

I need help solving for the equilibrium molarity of A and B please.

The concentration of A at equilibrium is about:
0.74M
0.13M
0.87M
Transcribed Image Text:The concentration of A at equilibrium is about: 0.74M 0.13M 0.87M
Calculating Equilibrium Concentrations and K
2 A(ag) + B(ag) ⇒ 4 C(ag) at 298K
Initial concentrations
[A] = 1.00 M, [B] = 1.00 M, and [C] = 0
At equilibrium [C] = 0.50 M
