Is the concentration of the reactants equal to the concentration of the products?

No, concentration of reactants and products are not necessarily equal in a dynamic equilibrium. That point is not reached when there is equal amount of products and reactants, but rather when the rate at which products are made is equal to the rate at which reactants are made.

What is the concentration of the reactant?

Reactant concentration is not uniform inside a catalyst particle. The reactant concentration is highest at the external surface and lowest at the center, forming a decaying profile from the outside to the inside. Product concentration has a reversed distribution.

How do you find the order of a reaction given concentration and time?

Take three consecutive points from the concentration versus time data. Calculate ΔyΔx for the first and second points. The concentration is the y value, while time is the x value. Do the same for the second and third point.

What is KC formula?

Kc is the equilibrium constant of a chemical reaction. For the reaction A+B=AB, the equilibrium constant Kc is defined as [AB]/[A][B]. Brackets denote reagent concentrations that must be given in order to compute Kc. As an example, we will calculate Kc for two reactions.

What is the concentration of reactants and products at equilibrium?

The system contains too much reactant and not enough product to be at equilibrium. The value of Qc must increase in order for the reaction to reach equilibrium. Thus, the reaction has to convert some of the reactants into products to come to equilibrium. 2.

What happens to the concentration of reactants during a reaction?

When the concentration of all the reactants increases, more molecules or ions interact to form new compounds, and the rate of reaction increases. When the concentration of a reactant decreases, there are fewer of that molecule or ion present, and the rate of reaction decreases.

How do you find K concentration from equilibrium?

Equilibrium Concentration

1. Step 2: Create the Ka equation using this equation :Ka=[Products][Reactants]
2. Ka=[H3O+][C7H5O2−][HC7H5O2] Step 3: Plug in the information we found in the ICE table.
3. Ka=(x)(x)(0.43−x) Step 4: Set the new equation equal to the given Ka.
4. 6.4×10−5=(x)(x)(0.43−x) Step 5: Solve for x. x=0.0052.

How is rate of reaction expressed in terms of concentration?

It is expressed in terms of concentration (amount per unit time) of the product. It means the concentration of the reactant is consumed in a unit of time. Nature of the reacting substance has a major contribution in the chemical reaction. Same condition reactions may have different rates depending on their identity of reactants.

How do you calculate equilibrium concentration in chemistry?

Steps to Calculate Equilibrium Concentration The first step is to write down the balanced equation of the chemical reaction. aA +bB cC + dD The second step is to convert the concentration of the products and the reactants in terms of their Molarity. The third step is to form the ICE table and

What happens when the concentration of reactants and products increases?

When the concentration of a reactant is increased, the chemical equilibrium will shift towards the products. When the concentration of a product increases, the chemical equilibrium will shift towards the reactants. 2. Why is it not necessary that at equilibrium concentration of reactants and products should be equal?

What is the rate of conversion of reactants to products?

Reactants are converted into products. It is expressed in terms of concentration (amount per unit time) of the product. It means the concentration of the reactant is consumed in a unit of time. Rate= change in concentration/change in time
