Reduce to lowest whole numbers (common denominator)2. This equation is called equation of law of chemical equilibrium. At equilibrium, the concentration of reactants is expressed as moles/lit so Keq = Kc and if it expressed as partial pressure then Keq = Kp. Example 1: Two moles of hydrogen reacts with 2 moles of iodine to form 2 moles of hydrogen iodide in a 10 lit vessel at 700 K temperature.

For the equilibrium: 2 BrCl (g) Br2 (g) + Cl2 (g) at 205 C, the equilibrium constant, Kc, is 0.143. At equilibrium, Rate of forwarding reaction = Rate of backward reaction. Here is the chemical equilibrium formula sheet Class 11. Types of Chemical Equilibrium. There are two types of chemical equilibrium: Homogeneous Equilibrium. Heterogeneous Equilibrium. Homogeneous Chemical Equilibrium. In Homogeneous Equilibrium, the reactants and the products of chemical equilibrium are all in the same phase. It can be further divided into two types: Inserts a new empty row above the selected cell of the sheet with a beige pattern. When a reversible reaction occurs in a closed system, a state of chemical equilibrium can be reached. Adjust coefficients1. Enthalpy - (TxEntropy). Part 1 of 3: Writing Chemical Formulas of Covalent CompoundsMemorize the prefixes for number of atoms. In naming compounds, Greek prefixes are used to indicate the number of atoms present for each element.Write the chemical symbol for the first element. When a compound has been written out, you must identify the elements and know their chemical symbols.Add the number of atoms as a subscript.
