The unit of rate constant of second order reaction is:
Correct answer: D. mole-1dm+3 sec-1
- A. mol dm-3 sec-1
- B. sec-1
- C. mol-2 dm+6
- D. mole-1dm+3 sec-1
Explanation
For reaction with order 2, the unit of rate constant is M-1 s-1 (or) L mol-1 s-1.

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.

The specific rate constant of a chemical reaction is the rate of the reaction when the concentration of the reactant is:
Which method for rate determination is useful for those reaction, which involve small volume change in solutions?
The rate of reaction involving ions can be studied by:
The 2nd order reaction becomes 1st order when:
For a reaction A+2B ----> C, rate is given by Rate = k[A][B], hence the order of the reaction is:
For the reaction A+B----->C+D, doubling the concentration of both the reactants increases the reaction rate by 8 times and doubling the initial concentration of only B simply doubles the reaction rate. The rate law for the reaction is:
