Question
In a reaction if the concentration of reactant A is tripled, the rate of reaction becomes twenty seven times. What is the order of the reaction?
Advertisements
Solution
Rate = `k[A]^alpha` .....(i)
27 × Rate = `k[3A]^alpha` .....(ii)
Dividing equation (ii) by equation (i), we get α = 3
∴ Order of reaction = 3
