1. (17.31) Calculate Kc for each of the following equilibria: H2(g)+I2(g)2HI(g)2SO2(g)+O2(g)2SO3(g)Kp=49at730.KKp=2.51010at500.K 2. (17.43) Gaseous ammonia was introduced into a sealed container and heated to a certain temperature: 2NH3(g)N2(g)+3H2(g) At equilibrium, [NH3]=0.0225M,[N2]=0.114M, and [H2]=0.342M. Calculate Kc for this reaction. 3. For the reaction H2(g)+CO2(g)H2O(g)+CO(g) at 700C,Kc=0.534. Calculate the number of moles of H2 that are present at equilibrium if a mixture of 0.300 mole of CO and 0.300 mole of H2O is heated to 700C in a 10.0L container
