For a reaction

A + B\, \to

Products, the rate of the reaction was doubled when the concentration of

A

was doubled. When the concentration of

A

and

B

were doubled, the rate was again doubled, the order of the reaction with respect to

A

and

B

are:

View answer and explanation

Correct option: C

1,0

Option C (1,0) is correct because doubling the concentration of A doubles the rate, indicating a first-order dependence on A, while changing B has no effect.

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
