The equilibrium constant
In a certain experiment a student starts with 0.862 atm of N2 and 0.373 atm of H2 in a constant-volume vessel at

Interpretation:
The partial pressure of the species present in the given equilibrium reaction is to be calculated with given
Concept introduction:
Equilibrium constant for gas phase reactions is written in terms of the partial pressures of the species present in the reactionas the concentration of gases is directly proportional to the partial pressures. The equilibrium constant in terms of partial pressure is denoted by
Equilibrium constant is the ratio of the concentration of reactants and products present in the chemical reaction.
For a general reaction:
The general formula for writing equilibrium expression for the reaction is given as:
Here,
A and B are reactants, C is products, and
For the general reaction:
The general formula for writing equilibrium expression for the reaction is given as:
Here,
A and B are reactants, C and D are products, and
Equilibrium constants of gas phase reaction are written in terms of partial pressures because concentration of gases is directly proportional to partial pressures.
