4. Equilibrium
A sealed 3.5 L container initially holds 0.0148 moles of hydrogen gas, 0.084 moles of solid iodine, and 0.0583 moles of hydrogen iodide gas. When equilibrium is reached, the concentration of hydrogen is 0.0065 M. Calculate the value of the equilibrium constant, Keq, for the reaction H2 (g) + I2 (s) → 2 HI (g). For the equilibrium constant, use a 1.0 M standard state, not a 1.0 atm standard state.

5. Equilibrium constant
A reaction takes place in a 5.0 L vessel at 267 K and has an equilibrium constant of 0.137. The standard heat of reaction is -226 kJ/mol. What is the value of the equilibrium constant at 331 K?
