Mamont248 [21]

Answer:

C. The reaction is energetically favorable.

Explanation:

The reaction which shows the removal of the terminal phosphate from the ATP is shown below:

ATP+H_2O\rightarrow ADP+P_i+\ energy

The Gibbs' free energy change of this reaction, \Delta G^0=-7.3\ kcal/mol

Hence, Option A is not correct.

It is a type of hydrolysis reaction in which water is being added to the molecule.

Hence, Option B is not correct.

The Gibbs' free energy change is negative which means that the reaction is energetically favorable.

Option C is correct.

At 25 oC, the rate constant for the first-order decomposition of a pesticide solution is 6.40 x 10-3 min-1. If the starting conc
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}
