Chemical Kinetics and Nuclear Chemistry question

2021 · 27 Jul · Shift 2 · Q21

JEE MainChemistryChemical Kinetics and Nuclear ChemistryNumerical+4 / −1
For the first order reaction A →\to→ 2B, 1 mole of reactant A gives 0.2 moles of B after 100 minutes. The half life of the reaction is ‾\underline{\hspace{2cm}}​ min. (Round off to the nearest integer). [Use : ln 2 = 0.69, ln 10 = 2.3] Properties of logarithms : ln xy = y ln x; ln⁡(xy)=ln⁡x−ln⁡y\ln \left( {{x \over y}} \right) = \ln x - \ln yln(yx​)=lnx−lny (Round off to the nearest integer)
