ANSWER

ANSWERFor first order reaction,

ANSWERFor first order reaction,A⟶B

ANSWERFor first order reaction,A⟶BRate =k×[A]

ANSWERFor first order reaction,A⟶BRate =k×[A]Given, rate =2.0×10−5molL−1s−1

ANSWERFor first order reaction,A⟶BRate =k×[A]Given, rate =2.0×10−5molL−1s−1[A] = Conc. of A = 0.01 M 

ANSWERFor first order reaction,A⟶BRate =k×[A]Given, rate =2.0×10−5molL−1s−1[A] = Conc. of A = 0.01 M So, 2.0×10−5=k×0.01

ANSWERFor first order reaction,A⟶BRate =k×[A]Given, rate =2.0×10−5molL−1s−1[A] = Conc. of A = 0.01 M So, 2.0×10−5=k×0.01k=0.012.0×10−5s−1

ANSWERFor first order reaction,A⟶BRate =k×[A]Given, rate =2.0×10−5molL−1s−1[A] = Conc. of A = 0.01 M So, 2.0×10−5=k×0.01k=0.012.0×10−5s−1 =2.0×10−3s−1

ANSWERFor first order reaction,A⟶BRate =k×[A]Given, rate =2.0×10−5molL−1s−1[A] = Conc. of A = 0.01 M So, 2.0×10−5=k×0.01k=0.012.0×10−5s−1 =2.0×10−3s−1For first order reaction,

ANSWERFor first order reaction,A⟶BRate =k×[A]Given, rate =2.0×10−5molL−1s−1[A] = Conc. of A = 0.01 M So, 2.0×10−5=k×0.01k=0.012.0×10−5s−1 =2.0×10−3s−1For first order reaction,t1/2=k0.693=2.0×10−30.693

ANSWERFor first order reaction,A⟶BRate =k×[A]Given, rate =2.0×10−5molL−1s−1[A] = Conc. of A = 0.01 M So, 2.0×10−5=k×0.01k=0.012.0×10−5s−1 =2.0×10−3s−1For first order reaction,t1/2=k0.693=2.0×10−30.693=346.5=347s
