Chemical Kinetics and Nuclear Chemistry question

2019 · 10 Apr · Shift 1 · Q14

JEE MainChemistryChemical Kinetics and Nuclear ChemistryMCQ+4 / −1
A bacterial infection in an internal wound grows as N'(t) = N0 exp(t), where the time t is in hours. A does of antibiotic, taken orally, needs 1 hour to reach the wound. Once it reaches there, the bacterial population goes down as dNdt=−5N2{{dN} \over {dt}} = - 5{N^2}dtdN​=−5N2. What will be the plot of N0N{{{N_0}} \over N}NN0​​ vs. t after 1 hour?
