Interpretation:
The equilibrium moles should be calculated to given the statement of equilibrium reaction at
Concept Introduction:
Kp and Kc: This equilibrium constants of gaseous mixtures, these difference between the two constants is that Kc is defined by molar concentrations, whereas Kp is defined by the partial pressures of the gasses inside a closed system.
Heterogeneous equilibrium: This equilibrium reaction does not depend on the amounts of pure solid and liquid present, in other words heterogeneous equilibrium, substances are in different phases.
Equilibrium concentration: If Kc and the initial concentration for a reaction and calculate for both equilibrium concentration and example using (ICE) chart and equilibrium constant and derived changes in respective reactants and products.
To find: Calculate the
