In general Photochemical reactions are of order:
Correct answer: D. 0
- A. 1
- B. 3
- C. 2
- D. 0
Explanation
The correct answer is (d) 0. In photochemical reactions, the rate is independent of the concentrations of the reactants (zeroth order) and instead depends on the intensity of light.

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
