Please Discuss here about this assignment.Thanks

Our main purpose here discussion not just Solution

We are here with you hands in hands to facilitate your learning and do not appreciate the idea of copying or replicating solutions.

sol iss ko mathype pe repaste kegye ga

mill jae ga sol

\[\begin{gathered}
  \frac{{dA(t)}}{{dt}} = {k_1}[M - A(t)] - {k_2}A(t) \hfill \\
   = {k_1}M - {k_1}A(t) - {k_2}A(t) \hfill \\
   = {k_1}M - A(t)[{k_1} + {k_2}] \hfill \\
  dt = \frac{{dA(t)}}{{{k_1}M - A(t)[{k_1} + {k_2}]}} \hfill \\
  \int {dt = \int {\frac{{dA(t)}}{{{k_1}M - A(t)[{k_1} + {k_2}]}}} }  \hfill \\
  t + C = \frac{{ - \ln [M{k_1} - At({k_1} - {k_2})]}}{{{k_1} - {k_2}}} + C \hfill \\
  t = \frac{{ - \ln [M{k_1} - At({k_1} - {k_2})]}}{{{k_1} - {k_2}}} \hfill \\
  \ln [M{k_1} - At({k_1} - {k_2})] =  - ({k_1} + {k_2})t \hfill \\
  [M{k_1} - At({k_1} - {k_2})] = {e^{ - ({k_1} + {k_2})t}} \hfill \\
   - At({k_1} - {k_2}) = {e^{ - ({k_1} + {k_2})t}} - M{k_1} \hfill \\
  A = \frac{{{e^{ - ({k_1} + {k_2})t}} - M{k_1}}}{{t({k_1} - {k_2})}} \hfill \\
  A = 0 \hfill \\

putting value in equation we have 0=0

Thus proved A(0)=0

Now  as  time goes on

  \frac{{{e^{ - ({k_1} + {k_2})t}} - M{k_1}}}{{t({k_1} - {k_2})}} = 0 \hfill \\
  M{k_1} = {e^{ - ({k_1} + {k_2})t}} \hfill \\
  {\lim _{t -  > \infty }}\frac{{{e^{ - ({k_1} + {k_2})t}}}}{{t({k_1} - {k_2})}} = \frac{{{e^\infty }}}{\infty } = \frac{1}{\infty } = 0 \hfill \\
\end{gathered} \]

This means that relatively quickly, the amount memorized becomes constant. That constant is always less than the total amount to be memorized
