# The law of mass action states which of the following?

## What does the law of mass action state?

Definition. The Law of Mass Action is the foundation of chemical kinetics and states that the rate of an elementary reaction (i.e., one that effectively occurs as a single step) is proportional to the product of the concentration of the reactants.

## What is Rate law and law of mass action?

The rate law is composed of rate constant and concentration of the reactants with the order of overall reaction. The law of mass action equation consists of a concentration of reactants and products raised to the power of the stoichiometric coefficient.

## Is law of mass action and law of chemical equilibrium same?

The law of mass action states that the rate of a reaction is proportional to the product of the concentrations of each reactant. … The law of mass action also suggests that the ratio of the reactant concentration and the product concentration is constant at a state of chemical equilibrium.

## Does law of mass action apply on the following reaction?

Yes, law of mass action apply here.

According to the law of mass action, mass of reactants is always equal to the mass of products. … of molecules in reactants is 4 and that of products is also 4. hence, the law is applicable here.

## Why is the law of mass action important?

The mass action law gives us a general method to write the expression for the equilibrium constant of any reaction. At this stage, you should be able to write the equilibrium expression for any reaction equation.

## What is active mass?

1 : the concentration of a reacting substance expressed usually in moles per liter. 2 : the concentration of the portion of a dissolved electrolyte that is dissociated into ions and hence is capable of carrying the electric current.

## What is positive catalyst give an example?

Positive Catalysts

Example: In the preparation of NH3 by Haber’s process Iron oxide acts as a positive catalyst and increases the yield of ammonia in spite of less reaction of Nitrogen.

## What is the difference between rate law and rate constant?

A rate law is an expression showing the relationship of the reaction rate to the concentrations of each reactant. … A large value of the rate constant means that the reaction is relatively fast, while a small value of the rate constant means that the reaction is relatively slow.1 мая 2013 г.

## Why is equilibrium dynamic in nature?

You may have learnt about reversible reactions. However, this equilibrium is said to be dynamic in nature. … This is because it consists of a forward reaction where the reactants react to give products and reverse reaction where the products can react to give back the original reactants.

## What is the law of chemical equilibrium?

n (chemistry) the principle that (at chemical equilibrium) in a reversible reaction the ratio of the rate of the forward reaction to the rate of the reverse reaction is a constant for that reaction. Synonyms: equilibrium law Type of: law, law of nature.

## What is meant by equilibrium position?

(noun) The point in a chemical reaction at which the concentrations of reactants and products are no longer changing.

## What is the mass action effect?

mass action in Chemical Engineering

Mass action is the effect when continuously adding reactants (= substances that are used in a reaction) to a reaction causes it to generate products continuously. … Mass action is the effect when continuously adding reactants to a reaction causes it to generate products continuously.

## What is meant by Le Chatelier’s principle?

chem the principle that if a system in chemical equilibrium is subjected to a disturbance it tends to change in a way that opposes this disturbance.
