Interpretation:
The option needs to be selected that does not affect the reaction rate.
Concept introduction:
The reaction rate is defined as the speed at which a
Answer to Problem 2STP
The correct option is (d): reactivity of products.
Explanation of Solution
Reason for correct option:
The reactivity of reactant molecules affects the
Reason for incorrect options:
Option (a): catalysts provide an alternate reaction pathway to obtain products that means catalysts increases the reaction rate by lowering the activation energy.
Option (b): surface area of reactants affects the rate of reaction; the rate of reaction increases with increase in surface area that allows more collisions to occur.
Option (c): With increase in concentration of reactants, the rate of reaction increases as higher concentration of reactant will results in more collisions between the reactants.
