Rate of first order reaction depends upon

For the reaction, 2A + B → Products, the following initial rates were obtained at various initial concentrations:

For the above reaction, the specific rate constant is

If initial concentration is reduced to 1/4th in a zero order reaction, the time taken for half the reaction to complete

The rate constant for the reaction 2N₂O₅ → 4NO₂ + O₂ is 3.0 × 10^–5 sec^–1. If the rate is 2.40 × 10^–5 mol litre^–1 sec^–1, then the concentration of N₂O₅ (in mol litre^–1) is

For a first order reaction we have k = 100 sec^-1. The time for completion of 50% reaction is:

In the first order reaction, 75% of the reactant disappeared in 1.386 h. Calculate the rate constant of reaction.

The decomposition of a substance follows first order kinetics. Its concentration is reduced to 1/8th of its initial value in 24 minutes. The rate constant of the decomposition process is

The reaction A → B follows first order kinetics. The time taken for 0.8 mole of A to produce 0.6 mole of B is 1 hour. What is the time taken for conversion of 0.9 mole of A to produce 0.675 mole of B?
