X + Y → Z. The rate equation for the chemical reaction above is \(\frac{-Δx}{Δt}\) = K[X]\(^2\)[Y].
The overall order of the reaction is?
The overall order of the reaction is?
0.0
1.0
2.0
3.0
Explanation
The overall order of a reaction is the sum of the exponents in the rate law.
The rate equation is \(\frac{-Δx}{Δt}\) = K[X]\(^2\)[Y].
The exponent for [X] = 2
The exponent for [Y] = 1
The overall order is the sum of the exponents = 2 + 1 = 3
