A substance A decomposes in solution by following the first order kinetics. Flask I contains 1 L of 1 M of solution of A and flask II contains 100 ml of 0.6 M solution of A. After 8 hrs the concentrationof A is flask I become 0.25 M. What will be time for concentration of A in flask II to become 0.3 M?

Consider a radioactive nuclide which follow decay rate given by A (t) = A_(0)2^(-(l//t_(0))), where A (f) is the fraction of radioactive material remaining after time t from the initial A_(0) at zero time. Let A_(1) be the fraction of orginal activity which remains after 120 hours. likewise A_(2) is the fraction of 200 hours. If (A_(1))/(A_(2))= 1.6, then the half-life (t_(0)) will be

Hydrolysis of methyl acetate in aqueous solution has been studied by titrating the liberated acetic acid against sodium hydroxide. The concentration of the ester at different times is given below. Show that it follows a pseudo first order reaction, as the concentration of water remains nearly constant (55 mol L^(-1)), during the course of the reaction. What is the value of k in this equation? Rate =k'[CH_(3) COOCH_(3) ][H_(2)O]

Radioactive decay is a statisticle process i.e., we cannot precisely predict the timing of a particular radioactivity of a particular nucleus . The nucleus can disintegrate immediately or it may take infinite time . Simply the probability of the number of nuclei being disintegrated at any instant can be predicted . the rate at which a particular decay process in a radioactive sample is directly proportional to the number of radioactive nuclei present and thus obeys first order kinetics . the factor dN/N expresses the fraction of nuclei decayed in time dt. t_(1//2) is the time in which half of the atoms are decayed and average life is the time for the nucleus to survive before decay . A freshly prepared radioactive source of half period 2 hour emits radiations on intensity which is 64 times of the permissible safe level. The minimum time after which it would be possible to work with this source is :
