Answer: Option (b) and (d) are correct.
Explanation:
An equilibrium reaction is defined as the reaction in which rate of forward reaction equals rate of backward reaction.
A photosynthesis reaction is the reaction in which plants in the presence of sunlight, water, and carbon dioxide make their own food.
- The amount of carbon dioxide consumed will be equal to the rate of formation of oxygen into the atmosphere.
Hence, the statement rate of formation of [tex]O_{2}[/tex] is equal to the rate of formation of [tex]CO_{2}[/tex] is true.
- Concentration of oxygen may remain constant but it will not decrease. Hence, the statement concentration of [tex]O_{2}[/tex] will begin decreasing, is false.
- As both oxygen and carbon dioxide are present in an equilibrium reaction, So, their concentration will not change.
Hence, the statement concentrations of [tex]CO_{2}[/tex] and [tex]O_{2}[/tex] will not change, is true.
- Concentration of carbon dioxide and oxygen will also depend on the limiting reagent. So, it is not necessary that the concentrations of [tex]CO_{2}[/tex] and [tex]O_{2}[/tex] will be equal.
Some amount of carbon dioxide might escape out into the air.
Hence, the statement concentrations of [tex]CO_{2}[/tex] and [tex]O_{2}[/tex] will be equal, is false.
