Answer:
The greater the energy required to break a bond, the stronger that bond must be.
Explanation:
Most iconic bonds are considerably stronger, more difficult to break, than covalent bonds.

The answer would be +208 J.
For the given chemical reaction, there will be no shift in the equilibrium due to addition of a catalyst.
<h3>Equilibrium shift</h3>
Catalyst is a substance that speeds up the rate of chemical reaction. The presence of catalyst in a chemical reaction do not affect the shift.
Hence for the given chemical reaction, there will be no shift in the equilibrium due to addition of a catalyst.

Answer:
C. Hb binds O2 more tightly than Mb.
Explanation:
<u>Hb and Mb are both oxygen carrier protiens which contain the heme group. Hb has 4 heme units in 1 moleucle which work via coperative effect. On the other hand, Mb has only one heme unit. </u>
<u>From above theory, statement A and B are correct.</u>
<u>Although the heme group of the Mb is identical to those of Hb, Mb has a higher affinity for carrying oxygen than hemoglobin.</u>
<u>Hence, Statement C is wrong.</u>
Thats why the function of hemoglobin is to transport oxygen and that of myoglobin is to store oxygen.
<u>When a curve is plotted between oxygen accepted and the pressure of the oxygen, Hb shows sigmoidal, whereas Mb shows hyperbolic oxygen saturation curves.</u><u> The statement D is correct.</u>
<u>Bohr effect and various factors decribe the statement : Hb-oxygen binding is dependent on physiological changes in pH, whereas Mb-oxygen binding is not. </u><u>The statement E is also correct.</u>
