Ammonia and oxygen react to form nitrogen monoxide and water, like this: Also, a chemist finds that at a certain temperature the equilibrium mixture of ammonia, oxygen, nitrogen monoxide, and water has the following composition:
Compound pressure at equilibrium
NH_3 65.3 atm
O_2 7.79 atm
NO 12.1 atm
H_2O 65.8 atm
calculate the value of the equilibrium constant Kp for this reaction. Round your answer to 2 significant figures.
Kp=

The value of the equilibrium constant Kp for this reaction is

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as K  

For the given balanced chemical reaction:

The expression for is written as:

The value of the equilibrium constant Kp for this reaction is

can you attach the

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
