The half life of a first order reaction is 0.5 min. Calculate time needed for the reactant to reduce to 20% and the amount decomposed in 55s.

The half-life period of any first order reaction:

The half life a first order reaction is1.7hr.How long will it take for 20% of the reactant to react?

The half life of a first order reaction is 10 years . The time taken by 10 g of the reactant to reduce its half is ______.

Half-life period of a firsr oder reaction is 56.5 min. Calculate rate constant in per second.

Half-life t_(1//2) of first order reaction is______

In a first order reaction , the concentration of the reactant is reduced to 12.5% in one hour. When was it half completed ?

The half life period of a first order chemical reaction is 6.93 minutes. The time required for the completion of 99% of the reaction will be (log2=0.301)

The half life of a first order reaction is 900 min at 820 K.Estimate its half life at 720 K if the energy of activation of the reaction is 250 kJ mol^(-1)
