Predict enthalpy for the reaction ch4(g)nh3(g)hcn(g)3 h2(g), from the data below: n2(g)+3 h2(g) 2 nh3(g) c(s, graphite) 2 h2(g)ch4(g) h2(g) 2 c(s, graphite) n(g)2 hcn(g) aho(1)91.8 kj ah(2)74.9 kj aho(3) 270.3 kj suggest two alternative strategies for finding the enthalpy of the target reaction. do you expect that they will produce identical results? justify any expected differences. [10 marks] question five predict the boiling point of water at a pressure of 1.5 atmospheres.
