What is the integrated rate equation for first order reaction?
For first-order reactions, the equation ln[A] = -kt + ln[A]0 is similar to that of a straight line (y = mx + c) with slope -k.
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.
What is the integrated rate equation for zero order reaction?
The integrated rate law for the zero-order reaction A → products is [A]_t = -kt + [A]_0. Because this equation has the form y = mx + b, a plot of the concentration of A as a function of time yields a straight line. The rate constant for the reaction can be determined from the slope of the line, which is equal to -k.
What is a first order rate constant?
The elimination rate constant (usually a first-order rate constant) represents the fraction of xenobiotics that is eliminated from the body during a given period of time.
How do you integrate first order?
Method of Integrating Factor.
- Calculate the integrating factor I(t). I ( t ) .
- Multiply the standard form equation by I(t). I ( t ) .
- Simplify the left-hand side to. ddt[I(t)y]. d d t [ I ( t ) y ] .
- Integrate both sides of the equation.
- Solve for y(t). y ( t ) .

What is first order equation?
A first-order differential equation is defined by an equation: dy/dx =f (x,y) of two variables x and y with its function f(x,y) defined on a region in the xy-plane. It has only the first derivative dy/dx so that the equation is of the first order and no higher-order derivatives exist.
How do you calculate rate constant k?
How to calculate the rate constant?
- The most obvious answer to the question “How to find the rate constant?” is to modify the equations for the rate of the reaction or its half-life.
- The dependence of the rate constant on temperature is well defined by the Arrhenius equation: k = A * exp(-E /(R * T)) .
