O False
Calculate a value for the equilibrium constant for the reaction
O2(g) + O (g) = O3(g)
given
NO2 (g) = NO(g) + O(g) K= 4.3*10-49
O3 (g) + NO (g) = NO2(g) + O2(g) K= 8.3 * 10-34
(Hint: When reactions are added together, the equilibrium expressions are multiplied.)
K =
The following reversible enzymatic reaction occurs in many areas of the body, but especially in red blood cells. The conversion of water and carbon dioxide into bicarbonate and hydrogen ions occurs through the action of an enzyme called carbonic anhydrase. Use the Law of Mass Action to predict which direction this equation will go under different circumstances.
CO2 + H2O ↔ H+ + HCO3-
Hyperventilating would increase the loss of carbon dioxide (CO2) from the blood. In what direction would the reaction above go in order to restore equilibrium? Left or right?

Is collision among molecules the only consideration for the molecules to react with one another? O Yes, collision between molecules is enough for the molecules to react with one another. O Collision between molecules which possess sufficient energy is always enough for the molecules to react with one another. O No, it is not. The molecules must also posses sufficient energy to react, and must have the proper spatial orientation. O Collision is not important. First, the molecules must have the proper spatial orientation.

Deficiency of dopamine results in Parkinson's disease. Administration of dopamine does not stop the symptoms of this disease because dopamine in the blood cannot cross the blood-brain barrier. The drug Dopa, however, does give relief from Parkinson's symptoms. It can pass through the blood brain barrier and is converted by enzymes inside brain cells to dopamine: соон CH2CHNH2 HO ÇOOH но- CO2 HO HO -CH2CH2NH2 Dopa Dopamine This reaction is an example of @ acid - base reaction 6 addition 6. substitution @ eliminationarrow_forward
