What can you conclude about these two reactions based on the chemical equations?

Reaction A: 6CO2 (g) + 6H2O (l) + sunlight → C6H12O6 (aq) + 6O2 (g)

Reaction B: 2H2 (g) + O2 (g) → 2H2O (g) + energy

A.

Reactions A and B are both exothermic.

B.

Reaction A is endothermic, and reaction B is exothermic.

C.

Reactions A and B are both endothermic.

D.

Reaction A is exothermic, and reaction B is endothermic

reaction A : 6 CO2 (g) + 6 H2O (l) + sunlight→ C6H12O6 (aq) + 6O2 (g)

reaction B: 2H2 (g) + O2 (g) → 2H2O (g) + energy

What we can conclude about the above chemical reaction is that

reaction A is endothermic, and reaction B is exothermic (answer B)

Explanation

Endothermic reaction is a reaction that absorb energy from its surrounding.

Exothermic reaction is a reaction that releases energy to the surrounding.

Reaction A : is endothermic since it absorb energy in form of sunlight from its surrounding.

Reaction B is a exothermic reaction since it releases energy to the surrounding.
