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.
