Chemical Kinematics



Chemical Kinematics is a branch of physical chemistry that deals with determination of rate of reaction. A reaction proceeds with disappearance of a reacants and formation of products. So, the rate of a chemical reaction can be measured in terms of rate of disappearance of reactants and formation of products.

Rate of reaction =  Chemical kinematics

 = mols litre-1 time -1

 

For reaction

 A + B             →             C

Rate of reaction can be measured in terms of rate of disappearance of A and B and rate of formation of C.

Rate of disappearance of A =Chemical kinematics

Rate of disappearance of B =Chemical kinematics

Rate of disappearance of C =Chemical kinematics

 

 

Note: -ve sign is used in change in concentration of reactant to make rate of reaction positive.
