Consider the reaction:
goldfiish [28.3K]

Answer:

K = Ka/Kb

Explanation:

P(s) + (3/2) Cl₂(g) <-------> PCl₃(g) K = ?

P(s) + (5/2) Cl₂(g) <--------> PCl₅(g) Ka

PCl₃(g) + Cl₂(g) <---------> PCl₅(g) Kb

K = [PCl₃]/ ([P] [Cl₂]⁽³'²⁾)

Ka = [PCl₅]/ ([P] [Cl₂]⁽⁵'²⁾)

Kb = [PCl₅]/ ([PCl₃] [Cl₂])

Since [PCl₅] = [PCl₅]

From the Ka equation,

[PCl₅] = Ka ([P] [Cl₂]⁽⁵'²⁾)

From the Kb equation

[PCl₅] = Kb ([PCl₃] [Cl₂])

Equating them

Ka ([P] [Cl₂]⁽⁵'²⁾) = Kb ([PCl₃] [Cl₂])

(Ka/Kb) = ([PCl₃] [Cl₂]) / ([P] [Cl₂]⁽⁵'²⁾)

(Ka/Kb) = [PCl₃] / ([P] [Cl₂]⁽³'²⁾)

Comparing this with the equation for the overall equilibrium constant

K = Ka/Kb

The balanced equation for the generation of sugar from sunlight water and co2 is
asambeis [7]

The balanced equation for the generation of sugar from sunlight water and CO₂ is

6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂

carbon dioxide + water → sugar + oxygen

<span>The process of photosynthesis occurs when the chlorophyll present in the leaves of plants absorb sunlight to make food in the presence of carbon dioxide (enters through the stomata of leaves) and water (absorbed from the roots). As a result of this reaction sugar and oxygen is formed. After that sugar is converted in to starch and oxygen is released into air.</span>

There are two stable isotopes of carbon, carbon -
nalin [4]

There is not enough information to determine anything about the relative abundances of the two isotopes.

<h3>What are isotopes?</h3>

Isotopes are atoms that have the same atomic number but different mass numbers. We know that all the isotopes of an element are not available to the same extent in nature.

Hence, from the average atomic mass of carbon, we can see that there is not enough information to determine anything about the relative abundances of the two isotopes.
