What happens to the amounts of reactant and products after a reaction has reached chemical equilibrium?

Answer 1

The "amounts" of reactants and products DO change in a reversible reaction. What doesn't change is the concentration of these reactants and products AT EQUILIBRIUM. And also what does not change is the total mass of the system.

Answer 2

The forward reaction goes at the same rate as the backwards reaction. But remember, ONLY in a closed system (so no products/reactants can escape!).

Think of it like digging a hole, and at the same rate, someone is filling the hole up. The deepness of the hole represents the position of equilibrium, eg the deeper the hole, means theres a bigger product ratio to reactants. But the depth stays the same, so it is like nothing is happening despite you continually digging the hole (the forwards reaction) and the other person filling up the hole (the backwards reaction).

Le Chatelier's principle helps you to understand the effect of concentration, temperature or pressure on a reversible reaction. (Reversible reactions are the types of reactions that can reach equilibrium.)

Answer 3

the reaction will take place only if a certain amount or compounds react with each other. the reaction will never proceed if the quantity if not specific.

Answer 4

Chemical equilibrium occurs when a reaction and a reverse reaction occur at the same rate. Once equilibrium is achieved, the amount of each product and reactant remains the same.

Answer 5

If a reaction is reversible, what are the relative amounts of reactants and products at the end of the reaction: c Some reactants and some products.

Answer 6

The law of mass conservation remain valid.
