# How does a 1st order reaction compare to a 2nd order?

## How does a 1st order reaction compare to a 2nd order?

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.

## Which equation is correct 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. This line can be graphically plotted as follows.

**What happens to the rate of first order reaction when the concentration is doubled?**

For a first order reaction, rate =k[A], when concentration of A is doubled, the rate becomes double.

### How do you convert differential equations to differences?

You can put y in terms of x by noting dy/dx=(dy/dt)/(dx/dt). For your first question, dy/dx=(0)/(−5(x−2))=0, so integrating, y=C for some constant C. Your second question is more complicated as it has both x and y in it, so I’m not sure this method will apply for that equation.

### Is the reaction first order or second-order with respect to the concentration of NO2?

The reaction is second order with respect to NO2.

**What are the differential equation of first order?**

A first order differential equation is an equation of the form F(t,y,y′)=0. F ( t , y , y ′ ) = 0 .

#### What are the examples of first order reaction?

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.

#### Why does higher concentration increase the rate of reaction?

Increasing the concentration of one or more reactants will often increase the rate of reaction. This occurs because a higher concentration of a reactant will lead to more collisions of that reactant in a specific time period.

**Which of the following is true for the first order reaction on doubling the concentration of the reactant?**

Solution : For a first order reaction, the rate of the reaction doubled as the concentration of the reactant is doubled because the rate is directly proportional to the concentration of the reactants.
