The time required for $$100\%$$ completion of a zero order reaction is:

A radioactive sample has a half-life period 1500 years. A sealed tube containing 1 g of the sample will contain _________ after 3000 year.

The half-life period of a radioactive substance is 20 minutes. The time taken for 1 g of the substance to reduce to 0.25g will be:

$$99\%$$ at a first order reaction was completed in $$32\:min.$$ when will $$99.9\%$$ of the reaction complete.(in min) :

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

The rate equation for a reaction, $$\displaystyle A\longrightarrow B$$ is $$\displaystyle r={ k\left[ A \right] }^{ 0 }$$. If the initial concentration of the reactant is $$a$$ $$mol.{ dm }^{ -3 }$$, the half-life period of the reaction is:

The time taken for $$10$$% completion of a first order reaction is $$20$$ min. Then, for $$19$$% completion, the reaction will take:

For a zero order reaction :

Speed of a chemical reaction depends on which of the following parameters?

The relationship between rate constant and half-life period of zero order reaction is given by:
