0.200mol of H2, 0.200mol of I2, and 0.200mol of HI were placed in a 1.00 L flask and allowed to come to equilibrium. The Kc value of the reaction at this temperature is 49.5. Determine the equilibrium concentrations of all species.

The lattice enthalpy (formation of ionic solid from ions in the gas phase) for agcl(s) is -916 kj/mol and the hydration enthalpy (dissolution of gaseous ions into water) is -850 kj/mol. how much heat (in joules) is involved in forming 1l of saturated agcl solution (1.8 × 10-4 g / 100 ml water) by dissolving agcl(s)? assume solution volume does not change much upon dissolution. the equations are given below. ag+(g) + cl−(g) æ agcl(s)
