How do you know if a reaction is first order?

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.

Why is a reaction first order?

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

How do you plot a first order reaction?

For a first-order reaction, a plot of the natural logarithm of the concentration of a reactant versus time is a straight line with a slope of −k. For a second-order reaction, a plot of the inverse of the concentration of a reactant versus time is a straight line with a slope of k.

What is 1st order kinetics?

First order kinetics occur when a constant proportion of the drug is eliminated per unit time. Rate of elimination is proportional to the amount of drug in the body. The higher the concentration, the greater the amount of drug eliminated per unit time.
