1.Write an equilibrium constant equation for the following reaction:
4NH3(g)+5O2(g)= 4NO(g)+6H2O(g)
2. What does the above [] mean in the above equation?
1. The equilibrium constant equation for the given reaction is written as follows:
Kc = [NO]^4[H2O]^6 / [NH3]^4[O2]^5
In this equation, Kc represents the equilibrium constant. The concentrations of the species involved in the reaction are written within square brackets. The coefficient in front of each species indicates the stoichiometric coefficient of that species in the balanced chemical equation.
2. The square brackets [] in the equation are used to denote the concentration of the species. Concentrations are typically expressed in moles per liter (mol/L) or molarity.
To write an equilibrium constant equation for a reaction, you need to express the concentrations of the reactants and products involved. The equilibrium constant is denoted by K, and it represents the ratio of the concentrations of products to the concentrations of reactants at equilibrium.
Using the reaction given in the question:
4 NH3(g) + 5 O2(g) = 4 NO(g) + 6 H2O(g)
The equilibrium constant equation for this reaction would be:
K = [NO]^4 * [H2O]^6 / [NH3]^4 * [O2]^5
Here, the square brackets [] represent the concentration of the species in moles per liter (M). The exponents indicate the stoichiometric coefficients of the balanced equation.
