Hello,
In this case, since the rate equation turns out as shown below due to the first-order kinetics:
Its integration results:
However, the rate constant is computed by considering the given half-life time as follows:
In such a way, the required time in minutes to diminish the concentration by 66.8% of the initial turns out:
Best regards.

The number of moles of sodium dichromate from the number of moles of oxygen atoms can be determined through stoichiometry. Using the molecular formula of the compound, Na2Cr2O7, 1 mole of the compound contains 7 moles of oxygen. Hence, 14 moles O2*(1 mole Na2Cr2O7/ 7 mole O2) is equal to 2 moles <span>Na2Cr2O7.</span>
