Chemical Kineti...

Effective collisions are those in which molecules must:

The rate constant of a reaction is 0.0693 $$min^{-1}$$. Starting with 10 mol, the rate of the reaction after 10 min is:

The activation energy for a simple chemical reaction $$A\, \rightarrow\, B\, is\, E_a$$ in the forward reaction. The activation energy of the reverse reaction:

The reaction $$A\, \rightarrow\, B$$ follows first-order kinetics. The time taken for 0.8 mol of A to produce 0.6 mol of B is 1 hr. What is the time taken for the conversion of 0.9 mol of A to produce 0.675 mol of B?

The activation energy for a simple chemical reaction, $$A\rightarrow{B}$$ is $$E_a$$ in forward direction. The activation energy for the reverse reaction:

80% of a first order reaction was completed in 70 min. How much it will take for 90% completion of a reaction ?

For a given reaction of the first order, it takes 15 minutes for the concentration to drop from 0.8 M to 0.4 M. The time required for the concentration to drop from 0.1 M to 0.025 M will be:

The rate of a chemical reaction generally increases rapidly even for small temperature increase because of a rapid increase in:

In a reaction, 5 g ethyl acetate is hydrolyzed per litre in the presence of dil. HCl in 300 min.If the reaction is of the first order and the initial concentration of ethyl acetate is  22 g $$L^{-1}$$, the rate constant of the reaction is:
