What will be the slope of a zero order reaction?
What will be the slope of a zero order reaction?
Because rate is independent of reactant concentration, a graph of the concentration of any reactant as a function of time is a straight line with a slope of −k. The value of k is negative because the concentration of the reactant decreases with time.
What is the slope of 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.
What is the difference between the zero order reaction and the first order of reaction?
A zero-order reaction proceeds at a constant rate. A first-order reaction rate depends on the concentration of one of the reactants. A second-order reaction rate is proportional to the square of the concentration of a reactant or the product of the concentration of two reactants.
Can first order reactions have a positive slope?
For a first order reaction to obtain a positive slope, a graph is plotted between −loge[A]vs.
How do you know if its a first order reaction?
To test if it the reaction is a first-order reaction, plot the natural logarithm of a reactant concentration versus time and see whether the graph is linear. If the graph is linear and has a negative slope, the reaction must be a first-order reaction.
What is the graph of zero order reaction?
Rate Laws from Graphs of Concentration Versus Time (Integrated Rate Laws)
| For a zero order reaction, | rate = k | (k = – slope of line) |
|---|---|---|
| For a 1st order reaction, | rate = k[A] | (k = – slope of line) |
| For a 2nd order reaction, | rate = k[A]2 | (k = slope of line) |
What’s the difference between first order and zero order elimination?
First order kinetics occur when a constant proportion of the drug is eliminated per unit time. Zero order: a constant amount of drug is eliminated per unit time.
What is the graph of first order reaction?
Graphical Representation of a 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. This line can be graphically plotted as follows. Thus, the graph for ln[A] v/s t for a first-order reaction is a straight line with slope -k.
What are the characteristics of first order reaction?
Characteristics of first order reaction → The rate constant does not depends upon the concentration of reactant. Half life period for a first order reaction is constant.
- The rate constant does not depends upon the concentration of reactant.
- Half life period for a first order reaction is constant.
