The Equilibrium Constant for the Gas Phase Reaction

A -33 kJ b -54 kJ c 54 kJ d 33 kJ e 13 J 20. Oxygen or compound molecules made from a variety of atoms eg.

Degrees Of Unsaturation Or Ihd Index Of Hydrogen Deficiency Index Chemistry Counting By 2 S

This special equilibrium constant is known as K P.

. Carbon dioxideA gas mixture such as air contains a variety of pure gases. K P takes the exact same form as K C. A pure gas may be made up of individual atoms eg.

For a specific reaction which of the following statements can be made about K the equilibrium constant. To avoid confusion between the two do not use brackets when expressing partial. A noble gas like neon elemental molecules made from one type of atom eg.

Gas is one of the four fundamental states of matter the others being solid liquid and plasma. A system whose reactants. The equilibrium constant at 427 o C for the reaction.

An equilibrium system that contains products and reactants in a single phase is a homogeneous equilibrium. An equilibrium constant calculated from partial pressures K_p is related to K by the ideal gas constant R the temperature T and the change in the number of moles of gas during the reaction. N 2 g 3H 2 g 2NH 3 g is K p 94 x 10-5.

Calculate the value of G o for the reaction at 427 o. Since pressure is directly proportional to concentration we can write our equilibrium expression for a gas-phase reaction in terms of the partial pressures of each gas.
