Calculate the standard enthalpy change for the reaction in which 6 moles of calcium oxide reacts with 3 moles of carbon dioxide to produce 2 moles of calcium carbonate. The equation for the reaction is:CaO(s) + CO2(g) → CaCO3(s)Given the standard enthalpy of formation values: ΔHf°[CaO(s)] = -635.09 kJ/mol, ΔHf°[CO2(g)] = -393.51 kJ/mol, and ΔHf°[CaCO3(s)] = -1207.44 kJ/mol.

A chemistry student wants to investigate the activation energy for a reaction between hydrogen and chlorine gases. The student measures the initial and final temperatures of the reaction mixture, and the rate of gas evolution. Based on this information, the student wants to calculate the activation energy of the reaction using the Arrhenius equation. What steps should the student follow to determine the activation energy of the reaction?
