Chemical Equilibrium – Ch. 6 1. Consider the following reaction: N (g) + 3 H (g) 2 NH (g) 2 2 3 a. Write the equilibrium expression (K and K ) p b. What is the value of K at 25°C if the equilibrium pressures for p N, H ...
Equilibrium is a state in which there are no observable changes as time goes by. Chemical equilibrium is achieved when: • the rates of the forward and reverse reactions are equal and • the concentrations of the reactants and products remain constant Physical equilibrium HO (l) HO (g) 2 2 ...
Section 15.1 – The Concept of Equilibrium • At equilibrium, two opposing processes are occurring at the same rate. • Ex: vapor pressure of a liquid in a closed container. Chemical Equilibrium • In chemical equilibrium, the rate at which the products are formed from reactants equals the rate ...
3. Chemical Equilibrium • Whenever we hear the word Equilibrium immediately a picture arises in our mind an object under the influence of two opposing forces. For chemical reactions also this is true. A reaction also can exist in a state of equilibrium balancing forward and backward reactions. A chemical ...
