A radioactive sample decays to half of its initial concetration in 6.9 – InterviewSolution

InterviewSolution

1.	A radioactive sample decays to half of its initial concetration in 6.93 minutes. It further decays half in next 6.93 minutes. The rate constant for the reaction is
Answer» `0.10 "MIN"^(-1)` `0.01 "min"^(-1)` `1.0 "min"^(-1)` `0.001 "min"^(-1)` SOLUTION :`K = (0.693)/(t_(1//2)) = (0.693)/(6.93) = 0.10 "min"^(-1)`
