Question

The equilibrium constant for the reaction H2 + I2 --> 2HI, is 54 at 425 degrees C. If the equilibrium mixture contains 0.030 M HI and 0.015 M I2, calculate the equilibrium concentration of H2.
........H2 + I2 ==> 2HI
E.......x..0.015....0.030
Plug into the Keq expression and solve for x.
Wouldn't Kc be equal to products/Reactants??
