1. When N Os(e) is heated to a particular temperature, it dissociates into N.Osg) and O.18) according to the reaction:

1,00g) + N20 g) + 0, 0) K 775

At the same temperature, the

N, O, dissociates: N 0,8) + N20 g) + 0,8) K4.00

When 4.00 mol of N,O() is heated in a 100 L reaction vessel to this temperature, the concentration of Olg) at equilibrium is 450 mol/L

a. What is the value of K for the overall reaction?

b. Find the concentrations of all the other species in the equilibrium system.

2. At 650 K, the reaction, MgCO,(s) – MgO(s) + CO2(9), has 0.026. A 10.0L container at 650 K has 1.0 g of MgO(s) and Co, at P 0.0260 atm at equilibrium. The container is then compressed to a volume of 0.100 L (temperature remains constant). Find the mass of MgCO, that is formed. Get Chemistry help Today
