What is the order of rate = k[NO]2[Br2].
2nd order?
If that is rate = k[NO]^2[Br]
It us second order with respect to NO and first order with respect to Br and 3rd overall.
To determine the order of a reaction, we examine the power to which the concentration of each reactant is raised in the rate equation. In this case, the rate equation is given as: rate = k[NO]2[Br2].
The order of a reaction with respect to a particular reactant is the exponent to which the concentration of that reactant is raised in the rate equation. In this case, the concentration of [NO] is raised to the power of 2 and the concentration of [Br2] is raised to the power of 1.
Therefore, the order of this reaction with respect to [NO] is 2, and the order with respect to [Br2] is 1. To find the overall order of the reaction, we simply sum up the individual orders.
In this case, the overall order of the reaction is 2 + 1 = 3. So, the reaction is third order.
