BIOSCIENCE ASSIGNMENT 2
PART A
1
a)
For a reaction at equilibrium, the concentrations/quantities of the reactants and products
is a constant. The rate of forward reaction is equal and opposite to that of backward reaction
(De Nevers, 2012, p. 217). For this to happen, the reaction must take place in a closed
system.
b)
Increasing the quantities of oxygen will shift the reaction to the right.
c)
Increasing the quantities of HbO in the equilibrium will shift the reaction to the left.
d)
The reaction will shift to the right.
e)
Le Chateliers’s Principle.
According to this principle, when a disturbance is created in a reaction in equilibrium, the
reaction will shift in such a manner as to counteract the effect of this disturbance (Pauling, 2014,
p. 409-410). A disturbance can be created by changing the concentrations of either the reactants
or products, change in temperature or pressure.

Kc= [ 6.93× 10−1 ]1

Kc= [ 6.93× 10−1 ]1

Kc=3.21 ×108

When the value of Kc is very large, it is an indication that the equilibrium
will favor the forward reaction and hence more of the products will be formed.
This type of can be termed as complete. However, when the value of Kc is very
small, it is an indication that the equilibrium will favor reverse reaction and hence
more of the reactants will be formed. Where the value of Kc approaches or is close
to 1, it indicates that the concentrations of both the reactants and products is close
to the same. The reaction may proceed in either way or the other. It’s called a
reversible reaction (Helmenstine, 2019).
5
The molecules of the reacting energy must collide with sufficient kinetic
energy so that they can break the bonds between the molecules. Heat can be added
to increase kinetic energy. Additionally, the atoms must collide in the correct
direction/orientation so that the reaction can take place. If this two criteria are met,
a reaction will take place.
