Activation energy of a chemical reaction can be determined by
What is the half-life of a radioactive substance if 87.5% of any given amount of the substance disintegrates in 40 minutes ?
A chemical reaction is catalyzed by a catalyst X. Hence X
For an exothermic reaction, the energy of activation of the reactants is
The half-life of a reaction is inversely proportional to the square of the initial concentration of the reactant. Then the order of the reaction is
Consider the following statements:
