Which gas is the reactant in the chemical reactions of photosynthesis?
2 answers:
Answer: carbon dioxide gas is the reactant in the chemical reactions of photosynthesis.
Explanation:
When plants make their own food with the help of sunlight, carbon dioxide and water then the process is known as photosynthesis.
Therefore, carbon dioxide gas is the reactant in the chemical reactions of photosynthesis.
The equation for photosynthesis reaction is as follows.

<h3>Further explanation</h3>Given
1.5 L container at STP
Heated to 100 °C
Required
The new pressure
Solution
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure).
So P₁ = 1 atm = 760 mmHg
T₁ = 273 K
T₂ = 100 °C+273 = 373 K
Gay Lussac's Law
When the volume is not changed, the gas pressure is proportional to its absolute temperature
Input the value :
P₂=(P₁.T₂)/T₁
P₂=(760 x 373)/273
P₂ = 1038.39 mmHg
