Activity 1 The equation for the combustion of butane gas is given below. 1.1 1.2 AH < 0 butane(g) + 1302(g) → 8CO2(g) + 10H2O(g) Define the term activation energy. Is the combustion reaction of butane exothermic or endothermic? Give reason for the answer. Draw a sketch graph of potential energy versus course of reaction for reaction above. 3 Clearly indicate the following on the graph: o Activation energy Heat of reaction (AH) Reactants and products Determine the empirical formula of butane gas if it consists of 82,76% and 17,24% hydrogen.
