Pure NOCl gas was heated at 230 °C in a 1 L container. At equilibrium the total pressure was 1.00 atm and the NOCl prssure was 0.27 atm. 2NOCl(g) &hArr 2NO(g) + Cl2(g) Calculate the partial pressure of NO and Cl2 in the system. Calculate the equilibrium constant KP.
Calculate the work done (in Joules) when 33.3g of tin dissolves in excess acid at 1.04 atm and 22 degrees C. Assume ideal gas behavior.
Calculate work (in kJ) when 422 g iron (III) oxide (MM = 159.7 g/mol) reacts with excess carbon to produce carbon dioxide gas at 445 K:
