Based on Le Chatelier's principle, when the equilibrium of a given reaction is disturbed due to some external factors like temperature, pressure or concentration, the equilibrium shifts in a direction to undo the effects of the change produced.
The given reaction is :-
CaCO3 (s) ↔ CaO (g) + CO2(g)
The forward reaction involves the formation of CaO and CO2 while the reverse involves formation of CaCO3.
If the concentration of the products CaO and CO2 is increased then the equilibrium will shift to a direction to counteract this increase. Hence, the products will tend to get used up and the reverse reaction will be favored.
Ans: B) the rate of reverse reaction will increase if the concentration of caO and CO2 is increased.
Answer:
Proteins.
Explanation:
Proteins (also called polypeptides) are large biological molecules which consists of one or more chains of amino acid. Proteins perform a series of functions which are catalysing metabolic reactions, DNA replication, providing structure to cells, transport molecules from one location to another within an organism etc.
Collagen consists of amino acids bound together to form a triple helix of elongated fibrils. It can be found in the skin, ligaments etc.
Enzymes are globular protein molecules which have the tertiary structure. They are generally rounded, "squashed" ball shape. Others include fibrous proteins which are long thin structures and are found in muscles and hair.
The pressure of the machine has to be reduced to 0.4 atm in order for the breathing machine to bring 500 ml of air into the lungs.
<h3>What is the relationship between volume and pressure?</h3>
Volume and pressure are inversely relate as given by the Boyle's law equation below:
The complete question is as follows:
<em>You Want To Design A Breathing Machine That Will Bring 500 ML Of Air Into The Lungs. You Begin With 100 ML Of Air At 2 atm Of Pressure. How Would You Change The Pressure In Your Machine To Accomplish Your Goal?</em>
From the question,
The change in pressure, will be:
Therefore, the pressure of the machine has to be reduced to 0.4 atm in order for the breathing machine to bring 500 ml of air into the lungs.
