Equilibrium Part 2

Calculating keq If you don’t know all of the [equilibrium], you must make an ICE table Fill in what you know & solve for all unknowns

Calculating keq A mixture of 5.00 x 10 -3 mol of H2 and 1.000 x 10 -2 mol of I2 are placed into a 5.000 L container at 448°C and allowed to come to equilibrium. Analysis of the equilibrium showed that [HI] was 1.87 x 10 -3 M. Calculate kc at 448°C.

Calculating keq H2 + I2 ⇄ 2HI I C E

Calculating keq 2SO3 ⇄ 2SO2 + O2 [SO3] initial = 6.09 x 10 -3 M [SO3] eq = 2.44 x 10 -3 M Calculate Kc

Calculating keq 2SO3 ⇄ 2SO2 + O2 I C E

Calculating keq 1.000 mol of H2 and 2.000 mol I2 are placed in a 1.000 L container. The kc for this reaction is 50.5. Calculate the equilibrium concentrations for H2, I2, and HI

Calculating keq H2 + I2 ⇄ 2HI I C E

Calculating keq PCl5 ⇄ PCl3 + Cl2 Kp = 0.497 (P PCl3) initial = 1.66 atm Calculate all equilibrium partial pressures

Calculating keq PCl5 ⇄ PCl3 + Cl2 I C E
