1.	Define the following termsi) Activation energyii) Rate of constantii) Collision frequencyiv) Order of reactionv) Half life period of reaction
Answer» The term Activation Energy was introduced in 1889 by Svante Arrhenius, a Swedish scientist. It is defined as the least possible amount of energy (minimum) which is required to start a reaction or the amount of energy available in a chemical system for a reaction to take place In chemical kinetics a reactionrate constantor reactionratecoefficient, k, quantifies therateof a chemical reaction. For a reaction between reactants A and B to form product C a A + b B → c C. the reactionrateis often found to have the form: Here k(T) is the reactionrate constantthat depends on temperature The collision frequency is defined as the number of collisions per unittime
