For example, in the reactions: 2HI <=> H2 plus I2 and H2 plus I2 <=> 2HI, the values of Q differ. When describing/comparing K as it's own value (K < 10 -3 or K > 10 3 ), saying products/reactants are favored means that's where the equilibrium is more likely to exist - if K < 10 -3, then there are more REACTANTS at equilibrium, which means that reactants are favored at equilibrium identify a reaction as product-favored or reactant-favored from the sign or magnitude of G rxn or K, respectively explain how G rxn differs from G rxn and discuss how G rxn changes during the course of a reaction. In his writing, Alexander covers a wide range of topics, from cutting-edge medical research and technology to environmental science and space exploration. the Q equation is written by multiplying the activities (which are approximated by concentrations) for the species of the products and dividing by the activities of the reactants. If the equilibrium constant value is a large number, like 100, or a very large number, like \(1 \times 10^{15}\), it indicates that the products (numerator) are a great deal larger than the reactants. If any component in the reaction has a coefficient, indicated above with lower case letters, the concentration is raised to the power of the coefficient. Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. If the value of K is greater than 1, the products in the reaction are favored. Sometimes, subscripts are added to the equilibrium constant symbol \(K\), such as \(K_\text{eq}\), \(K_\text{c}\), \(K_\text{p}\), \(K_\text{a}\), \(K_\text{b}\), and \(K_\text{sp}\).
