The energy needed to start the reaction is called :
Correct answer: B. Activation energy
- A. Potential energy
- B. Activation energy
- C. Kinetic energy
- D. Ionization energy
Explanation
The minimum amount of energy, required for an efective collision(start the reaction) is called activation energy.

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.

Let us consider the following reaction NO2(g) + CO(g)-> NO(g) + CO2(g) the rate equation of reaction is Rate = K[NO2]2 then the rate determining step is:
As the number of effective collisions between the reacting particles increases, the rate of reaction
The conversion of molecules of A to B follows a second order kinetics. Doubting the concentration of A will increase the rate of formation of B by a factor of:
Diazonium salt decomposes as: C6H5N2CI -> C6H5Cl + N2. At 0°C, the evolution of N2 becomes two times faster when the initial concentration of the salt is doubled. Therefore, it is:
