WebExample: Carbon reacts with oxygen to form carbon dioxide releasing 94.3kcals of heat in a single step. Carbon can also react in a two-step process of forming an intermediate carbon mono-oxide, which again is converted to carbon dioxide. ( ΔH = – Heat released) C + O 2 → CO + 26.0 kcals. CO + O 2 → CO 2 + 68.3kcals. WebHigher Chemistry Unit 3 Consolidation Exercises. Hyndland Chemistry Department.
