For a reaction a, A to Products , the ...

For a reaction a,` A to ` Products , the units of rate constant are given as `L mol^(-1) s^(-1)` . Write the rate expression .

Text Solution

Verified by Experts

Units of rate constant of the reaction
`=("units of rate")/(("Concentration")^(n))`
`L"mol"^(-1)s^(-1)=("mol"L^(-1)s^(-1))/(("mol"L^(-1))^(n))`
Therefore the value of n is equal to `2`.
Rate equation for the reaction is given as, rate =k[A]^(2)`.
