PLEASE HELP
As climbers ascend (go up) a mountain, the amount of oxygen in the atmosphere decreases. In the body, hemoglobin (Hb) in red blood cells binds with oxygen (O2) to form oxyhemoglobin (HbO2).
This equation can be used to model the equilibrium between hemoglobin , oxygen, and oxyhemoglobin.
Hb + O2 <--> HbO2
According to Le Chatelier, how would the equilibrium shift as the climbers ascend to higher altitudes?
Question 1 options:
It shifts to the left
It shifts to the right
It would not shift
There is not enough information to answer this question
Question 2 (1 point)
Is the following reaction endothermic or exothermic?
N2 + 2 H2 <-> 2NH3 + heat
Question 2 options:
endothermic
exothermic
Question 3 (2 points)
Stress was added to the following reaction and this was the result:
As4O6 + 6C <-> As4 + 6CO
The equilibrium shifted to the right and the reverse reaction decreased.
Select all factors that would have caused this observation.
Question 3 options:
CO was added to the system
As4 was added to the system
As4 was removed from the system
As4O6 was removed
Question 4 (1 point)
If CO2 was added to this system what would the outcomes for this reaction be?
CO2 + H2O <-> H2CO3
Question 4 options:
It would shift to the right, favor the forward reaction and the rate of reaction would decrease.
It would shift to the left, favor the forward reaction and the rate of reaction would increase.
It would shift to the right, favor the forward reaction and the rate of reaction would increase.
It would shift to the left, favor the reverse reaction and the rate of reaction would decrease.
