Ira Lisetskai [31]

Answer:

2.11\ * 10^{-2}  is the correct answer to the given question.

Explanation:

Given k=6.40 x 10-3 min-1.

According to the first order reaction .

The concentration of time can be written as

[\ A\ ]\ = \ [\  A_{0}\ ]  * e \ ^\  {-kt}

Here [\ A\ ]_{0} = Initial concentration.

So  [\ A\ ]_{0}= 0.0314 M

Putting this value into the above equation.

0.0314 \ *\ e^{6.40 x 10^{-3} \ *  \ 62.0  }

=0.211 M

This can be written as

=\ 2.11 *\ 10^{-2}
