What is the difference between the rate law and the integrated rate law?
Re: rate law vs integrated rate law
Rate Law is an expression that gives the reaction rate in terms of the concentration of species at any time. An Integrated Rate Law gives the concentration at any time after the start of the reaction.
What is the purpose of the integrated rate law?
We can use an integrated rate law to determine the amount of reactant or product present after a period of time or to estimate the time required for a reaction to proceed to a certain extent.
What is the integrated rate law for a first order reaction?

What is M and N in rate law?
If the exponent m is 1, the reaction is first order with respect to A. If m is 2, the reaction is second order with respect to A. If n is 1, the reaction is first order in B.
What is integrated rate?
An integrated rate law is an equation that expresses the concentrations of reactants or products as a function of time. An integrated rate law comes from an ordinary rate law.
What is the second order integrated rate law?
The Integrated Rate Law for a Second-Order Reaction
The reaction is second order with a rate constant equal to 5.76 × 10−2 L/mol/min under certain conditions.
Which step is rate determining?
The rate determining step
The overall reaction rate is determined by the rates of the steps up to (and including) the slowest elementary step. The slowest step in a reaction mechanism is called the rate determining or rate limiting step.
What is 1st order reaction?
A first-order reaction is a reaction that proceeds at a rate that depends linearly on only one reactant concentration.
How do you know if a reaction is first order?
If a plot of reactant concentration versus time is not linear but a plot of the natural logarithm of reactant concentration versus time is linear, then the reaction is first order.
