What is the order of the reaction with respect to NOBr?

The reaction of NOBr(g) to form NO(g) and Br2 (g) is second order: 2NOBr(g) → 2NO(g) + Br2 (g). The rate constant is 0.556 L mol−1 s−1 at some temperature.

What is the order of the reaction with respect to Br2?

Order with respect to Br2: Comparing experiments 1 and 2, [Br2] doubles, but the rate stays the same, so the reaction is zero order with respect to Br2.

How do you determine the order of a reaction from a reaction?

The overall order of the reaction is found by adding up the individual orders. For example, if the reaction is first order with respect to both A and B (a = 1 and b = 1), the overall order is 2.

What is a 2 order reaction?

A second order reaction is a type of chemical reaction that depends on the concentrations of one-second order reactant or two first-order reactants. This reaction proceeds at a rate proportional to the square of the concentration of one reactant, or the product of the concentrations of two reactants.

What is the concentration of NOBr?

At equilibrium the concentration of NOBr was found to be 0.250 M.

What is first order reaction example?

First-order reactions are very common. We have already encountered two examples of first-order reactions: the hydrolysis of aspirin and the reaction of t-butyl bromide with water to give t-butanol. Another reaction that exhibits apparent first-order kinetics is the hydrolysis of the anticancer drug cisplatin.

How do you know if its first or second order?

A first-order reaction rate depends on the concentration of one of the reactants. A second-order reaction rate is proportional to the square of the concentration of a reactant or the product of the concentration of two reactants.

What is the formula of second order reaction?

Second order reactions can be defined as chemical reactions wherein the sum of the exponents in the corresponding rate law of the chemical reaction is equal to two. The rate of such a reaction can be written either as r = k[A]2, or as r = k[A][B].

What is the reaction between no and Br2 and nobr?

The reaction is 2NO + Br2 → 2NOBr. The steps of the reaction are: N O + B r 2 → F a s t N O B r 2 N O B r 2 + N O → S l o w 2 N O B r

What is the rate of the reaction 2NO + Br2 → 2nobr?

The reaction is 2NO + Br2 → 2NOBr. The rate-determining step is N O B r 2 + N O → S l o w 2 N O B r the because it is the slowest step. According to rate law, the rate = k [NOBr2] [NO]. Hence, for the reaction 2NO + Br2 → 2NOBr, the rate law is k [NOBr2] [NO].

What is the Order of the reaction with respect to no?

The molecularity of the steps (1) and (2) are two each. The molecularity of the overall reaction is three. The overall order of the reaction is three. The order of the reaction with respect to NO is two. The molecularity of the steps (1) and (2) are two each. The overall order of the reaction is three.

Are fourth order reactions possible in organic chemistry?

They are possible, theoretically, and there have also been cases of fourth order reactions being reported in the past. However, the probability of such an occurance is low, extremely low because if the order of kinetics is 4 then it means that 4 molecules are reacting with the right orientation and activation energy, something rather uncommon.
