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.
