Activated complex is a substance which is ?

Correct answer: B. Unstable

  • A. Stable
  • B. Unstable
  • C. Can be isolated
  • D. Can exist as product

Explanation

Activated complex is an unstable combination of all the atoms involved in the reaction for which the energy is maximum. It is a short lived species and decomposes into the products immediately. It has a transient existence, that is why it is also called a transition state.

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.
