# 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.
