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=
myrzilka [38]

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

Draw the ketone produced from the oxidation of 2-pentanol.
natulia [17]
When 2-pentanol gets oxidized you end up with 2-pentanone. In this case, since we are oxidizing a secondary alcohol you end up with a ketone. They cannot be oxidized further than that. If it was a primary alcohol you would end up with an aldehyde.

You can find the mechanism as well the molecule formula of both 2pentanol and 2pentanone attached.
