What does the photosynthetic reaction of plants exhibit? [6CO2 + 6H2O + light → C6H12O6 + 6 O2] *EndothermicExothermicReversibleNone of these

Breaking Down the Problem

1. Identify the components of the photosynthetic reaction.
2. Determine the type of reaction based on the given options.

Relevant Concepts

1. Photosynthesis can be represented as: $6CO_2 + 6H_2O + \text{light} \rightarrow C_6H_{12}O_6 + 6O_2$
2. Classify the reaction under thermodynamic principles: endothermic versus exothermic.

Analysis and Detail

1. Endothermic Reactions: These reactions absorb energy (usually in the form of heat) from the surroundings. In photosynthesis, plants absorb light energy to convert carbon dioxide and water into glucose and oxygen.
2. Exothermic Reactions: These release energy into the surroundings. Since photosynthesis requires energy input from light, it does not fit into this category.
3. Reversible Reactions: While photosynthesis can be seen as part of a cycle (photosynthesis and respiration), the basic reaction itself is not reversible under standard conditions.
4. None of These: This would apply if none of the previous categories fit, which is not the case here.

Verify and Summarize

Since the process of photosynthesis absorbs light energy, it clearly categorizes as an endothermic reaction.

Final Answer

The photosynthetic reaction of plants exhibits an endothermic process.
