Answer:
The answer to your question is below
Explanation:
From reaction A we can conclude that it needs energy in order to generate products. If the reaction does not have enough energy, products will not be produced.
The second reaction shows us that some reactions release energy.
The first kind of reaction is called Endothermic while the second reaction is called Exothermic.
Answer: Reaction A is endothermic, and reaction B is exothermic.
Explanation:
Endothermic reaction is a reaction that absorb energy from its surrounding.
Reaction A :
input : 6H2O(l) + sunlight it absorbs sunlight
output : C6H12O6(aq) + 6O2(g)
Exothermic reaction is a reaction that releases energy to the surrounding.
Reaction B
input : 2H2(g) + O2(g)
output : 2H2O(g) + energy it releases heat energy so...yeah exothermic
