Which statement below correctly describes the relationship between Q and K for both reactions? Are these reactions spontaneous a
nikklg [1K]

Answer:

Q < K for both reactions. Both are spontaneous at those concentrations of substrate and product.

Explanation:

Hello,

In this case, the undergoing chemical reactions with their proper Gibbs free energy of reaction are:

A->B;\Delta _rG^o=-13 kJ/mol

C ->D ;\Delta _rG^o=3.5 kJ/mol

The cellular concentrations are as follows: [A] = 0.050 mM, [B] = 4.0 mM, [C] = 0.060 mM and [D] = 0.010 mM.

For each case, the reaction quotient is:

Q_1=\frac{4.0mM}{0.050mM}=80\\ Q_2=\frac{0.010mM}{0.060mM}=0.167

A typical temperature at a cell is about 30°C, in such a way, the equilibrium constants are:

K_1=exp(-\frac{-13000J/mol}{8.314J/mol*K*303.15K} )=173.8\\K_2=exp(-\frac{3500J/mol}{8.314J/mol*K*303.15K} )=0.249

Therefore, Q < K for both reactions. Both are spontaneous at those concentrations of substrate and product.

Best regards.

Explanation:

The temperature of the molten iron remained constant at 2750°C because of the heat absorbed to effect the phase change and not to change the temperature.

The heat of vaporization is a latent or hidden heat absorbed by substances that causes a phase change from liquid to gas.

  • In essence, the heat is used to break intermolecular bonds between the particles of the melted vat.
  • If enough heat is no supplied the molten vat will not boil off and become vapor.
  • In transitioning from liquid to gas, heat is absorbed by a body to effect the phase change.
  • When the body acquires enough heat, the particles are able to break off and boil.
  • At the 2750°C  mark, this is what is happening.

Which of the following is not an example of a science?
Cloud [144]
Geology is the science of Earth.

Ecology is the science of relationship between an organism and its environment.

Astronomy is the science of studying astronomical objects.

Whereas, Phrenology is the study of relating the size of human skull like its size, shapes e.t.c to his/her personality. So, its not a science as there is no scientific relationship between it.
