An effective collision between the molecules is primarily responsible for_.

Correct answer: C. Activated complex formation

  • A. Product formation directly
  • B. Reactant activation
  • C. Activated complex formation
  • D. Intermediate formation

Explanation

An activated complex is an unstable arrangement of atoms that has the highest energy. It is primarily formed as a result of the effective collision of molecules. Remember, ineffective collisions do not make an activated complex.

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.
