At 448°C the equilibrium constant (KC) for the reaction H2(g) + I2(g) ⇌ 2 HI(g) is 50.5. If a 2.0-L reaction chamber started with 0.200 mol of HI, 0.010 mol of H2, and 0.030 mol of I2, which of the following would you predict will occur as the reaction proceeds towards equilibrium? (a) The concentrations of H2 and I2 will increase. (b) The concentration of H2 will decrease while that of I2 will increase. (c) The concentration of HI will remain constant. (d) The concentration of HI will increase.
