Interpretation: Defining the chemical reversible reaction. Examining the question whether all
Concept introduction:A reversible chemical reaction can be defined as a reaction that can go in both forward and backward directions. The reactants can change into the products, and the products can change back into the reactants.This keeps on happening until it reaches equilibrium.
Equilibrium constant
The expression for equilibrium constant
Answer to Problem 12A
In principle all chemical reactions are reversible.
Yes, some reactions are more likely to occur in one direction.
Explanation of Solution
All chemical reactions are reversible, at least in principle. Equilibrium is dynamic in nature; it may appear that no change is happening. But actually, both forward and backward reaction occurs at same rate. Reactants get combined to form the products and the products combe to form the reactants.
Some chemical reactions are likely to occur in one direction. These reactions are called irreversible reactions.Irreversible reactions are marked by their high value of equilibrium constant
In a complete combustion reaction, fuel (generally hydrocarbons) and oxygen reacts to form carbon dioxide and water. These two products cannot react to regenerate the fuel and oxygen, so the reaction is irreversible.
In principle, all chemical reactions are reversible.
Yes, some reactions are more likely to occur in one direction.
