Question

At a particular temperature, Kc = 54 for the reaction H2(g) + I2 (g) <=> 2 HI(g).
One mole of HI is placed in a 3.0-L container. What would be the equilibrium concentration of HI?

Answer 1

See below.

Answer 2

for this one, when we set up the ice chart, and we have the M of HI, and we have to subtract x, would we subtract 2x because the mols of HI is two?

Answer 3
