Be sure to answer all parts. write the balanced equations corresponding to the following rate expressions: a) rate = − 1 3 δ[ch4] δt = − 1 2 δ[h2o] δt = − δ[co2] δt = 1 4 δ[ch3oh] δt (click in the answer box to activate the palette. do not include states of matter.) b) rate = − 1 2 δ[n2o5] δt = 1 2 δ[n2] δt = 1 5 δ[o2] δt (click in the answer box to activate the palette. do not include states of matter.) c) rate = − 1 2 δ[h2] δt = − 1 2 δ[co2] δt = − δ[o2] δt = 1 2 δ[h2co3] δt (click in the answer box to activate the palette. do not include states of matter.)

Answer : The balanced equations will be:

(a)

(b)

(c)

Explanation :

The general rate of reaction is,

Rate of reaction : It is defined as the change in the concentration of any one of the reactants or products per unit time.

The expression for rate of reaction will be :

From this we conclude that,

In the rate of reaction, A and B are the reactants and C and D are the products.

a, b, c and d are the stoichiometric coefficient of A, B, C and D respectively.

The negative sign along with the reactant terms is used simply to show that the concentration of the reactant is decreasing and positive sign along with the product terms is used simply to show that the concentration of the product is increasing.

Now we have to determine the balanced equations corresponding to the following rate expressions.

(a)

The balanced equations will be:

(b)

The balanced equations will be:

(c)

The balanced equations will be:

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.
