Answer:

[tex]t=5.84\times 10^{-5}s[/tex]

Explanation:

  • First rearrange the whole equation by keeping t in one side and rest parameters in another side of equation
  • Then plug-in all the given values for each parameters and get the solution

[tex]ln(\frac{A}{B})=-kt[/tex]

or, [tex]t=\frac{1}{-k}\times ln(\frac{A}{B})[/tex]

Now plug-in all given values:

[tex]t=\frac{1}{-4.80\times 10^{4}s^{-1}}\times ln(\frac{1.00\times 10M}{1.65\times 10^{2}M})[/tex]

So, [tex]t=5.84\times 10^{-5}s[/tex]
