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 is equal to the rate of formation of
is true.
- Concentration of oxygen may remain constant but it will not decrease. Hence, the statement concentration of
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 and
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
and
Some amount of carbon dioxide might escape out into the air.
Hence, the statement concentrations of and
will be equal, is false.
