Question

what is the rate of first order reaction after two half lives if initial rate of reaction is r? ​

Answer 1

Answer:

integrated ratelaw[A] = −kt + [A]0ln[A] = −kt + ln[A]0plot needed for linear fit of ratedata[A] vs. tln[A] vs. trelationship between slope of linear plot and rate constantk = −slopek = −slopehalf-lifet1/2=[A]02kt1/2=0.693k
