At a certain temperature the equilibrium constant Kc for thi

At a certain temperature, the equilibrium constant, Kc, for this reaction is 53.3.

H2(g) + I2(g) <=> 2HI(g) Kc=53.3

At this temperature, 0.500 mol of H2 and 0.500 mol of I2 were placed in a 1.00-L container to react. What concentration of HI is present at equilibrium?

At first I got 3.65M, but that\'s wrong, so I don\'t know what I\'m doing wrong. please help!

Solution


0.5-X + 0.5-X = X2

SO 53.3=[2x]^2/[0.5-x]^2

2x/0.5-x=7.3

x=0.646 M
