Assuming that the volume of the system is constant, derive the average rate of the system `R to p` in terms of R and P. [time ='t' sec] [R =reactant, P= product].

Explanation

`R to P `
At time `'t'_(2) 'C' is " "[R_(1)]" "[P_(1)]" "`Concentration
At time `'t'_(2)'C'is " "[R_(2)]" "[P_(2)]`
Charge in `'C' is " "[R_(2)-R_(1)]" "[P_(2)-P_(1)]`
`therefore` Acverage rate of reaction `=(-(R_(2)-R_(1)))/((t_(2)-t_(1)))=(+(P_(2)-P_(1)))/(t_(2)+t_(1))`
