The reaction

2A + B + C \to D + E

is found to be first order in

A

, second in

B

and zero order in

C

. What is the effect on the rate of increasing concentration of

A

B

and

C

two times?

View answer and explanation

Correct option: B

8 times

Option B (8 times) is correct because the rate is first order in A and second order in B, so doubling A doubles the rate, and doubling B quadruples the rate, resulting in a total increase of 2 * 4 = 8 times.

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)
