How does the surface metabolism model of chemical evolution differ from the prebiotic soup model? see section 2.4 ( page 70) ?

1 answer:

3 0

The surface metabolism model evokes mineral catalysts. Surface metabolism model dissolved gases in contact with minerals lining the walls of the deep-sea hydrothermal vents and formed more complex, organic molecules while Prebiotic soup model is molecules in atmosphere or from meteorites condensed in the ocean which led to the formation of more complex molecules.

A sample of O2(g) is placed in an otherwise empty, rigid container at 4224 K at an initial pressure of 4.97 atm, where it decomp

frutty [35]

Answer:

The value of $K_p$ at 4224 K is 314.23.

Explanation:

$O_2(g)\rightleftharpoons 2O(g)$

Initially

4.97 atm 0

At equilibrium

4.97 - p 2p

At initial stage, the partial pressure of oxygen gas = =4.97 atm

At equilibrium, the partial pressure of oxygen gas = $p_{O_2}=0.28 atm$

So, 4.97 - p = 0.28 atm

p = 4.69 atm

At equilibrium, the partial pressure of O gas = $p_{O}=2p=2\times 4.69 atm=9.38 atm$

The expression of $K_p$ is given as :

$K_p=\frac{(p_{O})^2}{(p_{O_2})}$

$K_p=\frac{(9.38 atm)^2}{0.28 atm}=314.23$

The value of $K_p$ at 4224 K is 314.23.
