How to calculate rate law

How do you determine rate law?

In order to determine a rate law we need to find the values of the exponents n, m, and p, and the value of the rate constant, k. If we are given the reaction orders for a reaction, we have the values of the coefficients we need to write the rate law.

How do you calculate rate order?

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. We call this an overall second order reaction.

How do you calculate initial rate of reaction?

The initial rate of a reaction is the instantaneous rate at the start of the reaction (i.e., when t = 0). The initial rate is equal to the negative of the slope of the curve of reactant concentration versus time at t = 0.

What is the rate law expression?

the rate law can be expressed as: Rate = k[A]y[B]z. The proportionality constant, k, is known as the rate constant and is specific for the reaction shown at a particular temperature. The rate constant changes with temperature, and its units depend on the sum of the concentration term exponents in the rate law.

What is the first order of reaction?

A first-order reaction is a reaction that proceeds at a rate that depends linearly on only one reactant concentration.

How do you calculate rate per 1000?

Divide the population size by one thousand. In the example, 250,000 divided by 1,000 equals 250, which is called the quotient, the result of division. Divide the number of occurrences by the previous quotient. In the example, 10,000 divided by 250 equals 40.

What is the rate of consumption?

Re: Rate of formation/consumption

The rate of formation generally refers to one of the products (d[B]/dt, for example). The rate of consumption is the rate at which one of the reactants is being consumed at the beginning of the reaction.
