WebJul 17, 2024 · Chemical Kinetics Class 12 Chemistry MCQs Pdf. 1. The half life period of first order reaction is 1386 seconds. The specific rate constant of the reaction is. 2. The rate constant of a reaction A → B is 0.6 × 10 3 mole per second. The number of reacting particles (molecules, atoms, or ions) that collide simultaneously in a rate determining step to form a product is called molecularity of a reaction. In general, the molecularity of simple reactions is equal to the sum of the number of molecules of reactants involved in the balanced … See more The order of reaction is defined as “ the sum of the coefficients (or power ) of the reacting species that are involved in the rate equation for the reaction.” The … See more Let us consider a general reaction: aA + bB + cC → Product Let active moles of A, B and C be α, β and γ respectively. Then the rate of reaction may be given as: Rate = … See more WebOrder of Molecularity.
