# What is the rate law for reaction 1?

## What is the rate law for reaction 1?

Orders of Reactants & of the Reaction When the order is 1, or n = 1, this means that the relationship between the concentration of Reactant A and the rate of the reaction is directly proportional. When A increases, R will increase proportionally. If A doubles, R doubles as well.

What is rate law explain with example?

Rate law is the mathematical expression which describes the rate of reactions in terms of concentration of reactants as determined experimentally.. For example, we have a chemical reaction : 2NO2(g)+F2(g)→2NO2F(g)

### What is the expression for the rate law for a 2 b \Rightarrow C?

A+2B→C, the rate equation for reaction is given as Rate=[A][B]. If the concentration of A is kept constant while B is doubled.

How do you write the reaction rate equation?

For a generic reaction aA+bB→C aA + bB → C with no intermediate steps in its reaction mechanism (that is, an elementary reaction), the rate is given by: r=k[A]x[B]y r = k [ A ] x [ B ] y . For elementary reactions, the rate equation can be derived from first principles using collision theory.

#### How do you determine the rate of a reaction?

The rate of a chemical reaction can also be measured in mol/s. For example, if two moles of a product were made during ten seconds, the average rate of reaction would be 2 ÷ 10 = 0.2 mol/s.

How do you write a rate law equation?

A rate law relates the concentration of the reactants to the reaction rate in a mathematical expression. It is written in the form rate = k[reactant1][reactant2], where k is a rate constant specific to the reaction. The concentrations of the reactants may be raised to an exponent (typically first or second power).

## What is a 1st order reaction?

Definition of first-order reaction : a chemical reaction in which the rate of reaction is directly proportional to the concentration of the reacting substance — compare order of a reaction.
