A first order reaction is carried out with an initial concentration of 10 mole per litre and

80\%

of the reactant changes into the product. Now if the same reaction is carried out with an initial concentration of 5 mol per litre the percentage of the reactant changing to the product is:

View answer and explanation

Correct option: B

Option B (80) is correct because the percentage of reactant changing into product in a first-order reaction is independent of the initial concentration.

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
