WebRate constant in case of first order reaction is : A Inversely proportional to the concentration units B Independent of concentration units C Directly proportional to … WebIf the reaction is of the first order, doubling the reactant concentration will double the reaction rate. In second-order reactions, doubling the concentration of the reactants will quadruple the overall reaction rate. For third-order reactions, the overall rate increases by eight times when the reactant concentration is doubled. Rate Constants WebThe rate constant for the first order decomposition of H 2 O 2 is given by the following equation:log k =14.2 1.0 × 104 K / TCalculate E a for this reaction and rate constant k of its half life period be 200 minutes.
