For a first order reaction

{X_{\left( g \right)}} \to {Y_{\left( g \right)}} + {Z_{\left( g \right)}}

. The half – life period is 6.93 min. The time required for the completion of 99% of the chemical reaction will be

View answer and explanation

Correct option: C

46.06 min

Option C (46.06 min) is correct because it is the time required for 99% completion calculated using the first-order kinetics equation and the given half-life.

If the reaction rate at a given temperature becomes slower then

\frac{1}{{{{\left[ A \right]}^2}}}

vs times are a straight line. Order of reaction is The rate constant

\left( {k'} \right)

of one of the reaction is found to be double that of the rate constant

\left( {k''} \right)

of another reaction. Then the relationship between the corresponding activation energies of the two reaction
