Higher order reactions have a half-life _.
Correct answer: B. Different from first-order reactions
- A. Same as the first-order reaction
- B. Different from first-order reactions
- C. Directly proportional to the concentration of reactants
- D. None of these options are correct
Explanation

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.
