Reaction H2 + Cl2 -> 2HCl is:
Correct answer: E. Zero order
- A. Second order
- B. First order
- C. Half order
- D. Third order
- E. Zero order
Explanation
The correct answer is e) Zero order. The given reaction H2 + Cl2 -> 2HCl is a zero-order reaction, where the reaction rate is independent of the concentrations of the reactants.

About Thermochemistry and Energetics of Chemical Reactions
Thermochemistry measures energy changes in chemical reactions and distinguishes exothermic from endothermic processes. Work covers systems, surroundings and state functions, internal energy, the first law of thermodynamics, enthalpy and Hess's law, including the sign conventions used when heat enters or leaves a system.
