Which of the following statement is not correct for the reaction:

4A + B \to 2C + 2D

View answer and explanation

Correct option: A

The rate of disappearance of ‘B’ is twice the rate of appearance of ‘C’

Option A (The rate of disappearance of ‘B’ is twice the rate of appearance of ‘C’) is correct because the stoichiometry of the reaction dictates that the rate of disappearance of B is half the rate of appearance of C.

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
