Activity: Note: Use 4 decimal places. Write the (a)Given, (b)Required, and (c)Solution. Box the final answer. A. Write the general equilibrium expression (kc or kp) and calculate the required for the following reactions. 1. Evaporation of water H2O + H2Og Required: a. kc or ky expression b.kp at equilibrium: PH2O(g) = 2.3 kPa 2. Haber Process N2(g) + 3H2(g) + 2NH3(g) Required: a. a. k, or kp expression b.kp PHz PNH3( at equilibrium: PN2) = 0.432 atm = 0.928 atm = 2.24x10-3 atm 3. Thermal decomposition of calcium carbonate CaCO3(s) Cao s) + CO2(g) Required: a. kc or kp expression b. kp at equilibrium: PCO2 = 5.7292 MPa
