In a chemical reaction, if the reactant requires a high amount of activation energy, then what is the behaviour of the reaction?(a) Fast(b) Slow(c) Instantaneous(d) Doesn’t depend on activation energyThis question was posed to me in class test.My query is from Collision Theory of Chemical Reactions in division Chemical Kinetics of Chemistry – Class 12

Answer» CORRECT choice is (b) Slow

For explanation: The reaction occurs slowly only if the reactants are slow, so if the reactants are slow we have to provide a high AMOUNT of ACTIVATION energy (Ea) to the reactants. This ENHANCES the SPEED of the reactants in the reaction and to form products.
