Show that the rate of first order reaction is doubled when concentration of the reactant is doubled.

Answer»

SOLUTION :Consider FIRST order reaction `A to P`
`r_(1) = k[A]^(1) "" ….. (1)`
When CONCENTRATION is doubled
`r_(2) = k[2A]^(1) "" r_(2) = 2k [A} "" …(2)`
Comparing equation (1) and (2)
`r_(2) = 2r`
