Question

For the reaction A B the following graph was obtained. The time required (in seconds) for the concentration of A to reduce to 2.5 ~g ~L ⁻¹ (if the initial concentration of A was 50 ~g ~L ⁻¹ ) is _______ (Nearest integer) Given : 2=0.3010 [We can assume in a hypothetical situation that the graph is correct, assuming its first order reaction, in reality the question is wrong.]

Correct answer: 0

As it is difficult to predict order using data provided in graph. For specific time interval 0-5 sec , 5-10 sec and 10-15 sec . order comes to be zero, but graph is not a straight line. Assuming 1^ st order kinetics aligned & K = 1 t ~A ₀ ~A _ t & ~K = 1 10 40 20 aligned Time required to reduce to 2.5 ~g / L aligned & K = 1 t 50 2.5 & 1 10 2= 1 t 20 & t = 1.3010 10 0.3010 =43.3 sec aligned
