Answer 1

Part A 1 mole of methane provide energy value of 803 kJ. Determine the amount of energy released by 21.4 mol of methane as shown below: kJ Energy produced by methane (in kJ)= 21.4 mól x 803- mol 17184.2 kJ %3D Hence, energy produced by combustion of 21.4 mol of methane is 17184.2 kJ Part C The graphs for exothermic and endo thermic reactions are as follows: Exothermic Reaction Endothermic Reaction Transition state Transition state Activation energy -Activation energy Energy absorbed Energy of the product Energy of the reactant Energy released Energy of the product Energy of the reactant Direction of the reaction Direction of the reaction Energy Energy

Align the given statements in respective bins as shown below: Exothermic reactions Endothermic reactions Heat is released to the Heat of the reaction is absorbed from environment. surrounding surrounding environment. the The activation energy for the forward reaction is less than The activation energy for the forward reaction is greater than that for the reverse reaction. that for the reverse reaction. The energy of the reactants is higher than the energy of the product formed The energy of the reactants is lower than the energy of the product formed
