Nitrogen monoxide, a colorless gas, dissociates via an equlibrium process to form nitrogen gas and oxygen gas, when it is heated to very high temperatures. At these conditions, the equlibrium is said to favor the products. What does this mean in terms of the magnitude of the value of the K expression and the quantities of each species present?
