Explain the terms with suitable exapmples. Molecularity of a reaction

1.	Explain the terms with suitable exapmples. Molecularity of a reaction
Answer» Molecularity of a reaction : Zero order reaction is the reaction in which rate of reaction does not depends on the concentration of reactants. `R to P` Rate `(-d[R])/(dt)=k [R]^(@)` Rate `=(-d[R])/(dt)` `d[R]=-k.dt` Intergratinng on both sides `[R] =-kt +I-(1)` I = Intergration constant At `t=0 to R=[R]_(0)` initial concentration `I=[R]_(0)` Substituting `I=[R]_(0)` in the above equation (1) `[R] =-kt+[R]_(0)` `k=([R]_(0)-[R])/(t)` This is the integrated rate equation for a zero order reaction.
