0.0030
0.0030 is the equilibrium constant for the reaction at this temperature.
The reaction is as follows:
N2(g)+ 3 H2(g) ⇌ 2 NH3(g)
At equilibrium, the concentrations of the different species are as follows.:
[NH3] = 0.105 M
[N2] = 1.1 M
[H2] = 1.50 M
The equilibrium constant for the reaction is given as follows:
Keq = [NH3]² / [N2] [H2]³
Keq = (0.105)² / [1.1] [1.50]³
Keq = 0.00296 or 0.0030
The equilibrium constant for the reaction at this temperature is 0.0030.
What is an equilibrium constant?
- The value of a chemical reaction's reaction quotient at chemical equilibrium, a condition that a dynamic chemical system approaches when enough time has passed and at which its composition has no discernible tendency to change further, is the equilibrium constant for that reaction.
Changes in equilibrium constant:
- If the concentrations of the substances present in the equilibrium are adjusted, the equilibrium constants remain unchanged.
- An equilibrium constant can only be altered by a change in temperature.
- If you adjust the concentration of something present in the mixture, the equilibrium position will change.
