It rate constant

K = 2.3 \times {10^{ - 5}}L\,.\,mo{l^{ - 1}}.\,{S^{ - 1}}

, identify order of reaction

View answer and explanation

Correct option: D

Option D (2) is correct because the order of a reaction can be determined from the units of the rate constant, and the given units correspond to a second-order reaction.

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

\left( {{{E'}_a}\;\mathrm{and}\;{{E''}_a}} \right)

can be represented as Acid hydrolysis of sucrose is a Order of radioactive disintegration reaction is Temperature coefficient of a reaction is 2. When temperature is increased from

30^\circ C\;to\;100^\circ C

, rate of the reaction increases by
