Solve for t In(A/B) -kt where B-1.65 x 102 M A 1.00 x 10 M. k-4.80 x 104s* and t=

Answer 1

Answer:

$t=5.84\times 10^{-5}s$

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

$ln(\frac{A}{B})=-kt$

or, $t=\frac{1}{-k}\times ln(\frac{A}{B})$

Now plug-in all given values:

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

So, $t=5.84\times 10^{-5}s$
