Ammonium carbamate solid (NH4CO2NH2) decomposes at 313 K into ammonia and carbon dioxide gases. At equilibrium, analysis shows that there are 0.0451 atm of CO2, 0.0961 atm of ammonia, and 0.159g of ammonium carbamate. a) Write the balanced equation for the decomposition of one mole of NH4CO2NH2. b) Calculate K at 313 K.
