Answer:
A. When temperature increases, the number and energy of collisions between particles increases, which increases the rate of the reaction.
Explanation:
The reaction rate measures the speed with which a reaction proceeds. Based on the collision theory of reaction rates, the rate of a given reaction depends on the number of collisions per time and how successful or effective the collisions are.
Reaction rate in view of the collision theory is very related to concentration and temperature. Both properties are directly proportional to the rate of a reaction.
As temperature increase, the rate of the reaction increases due to the number of effective collisions and the energy of between colliding particles.
Answer:
Hydrogen ion [H]
Explanation:
overall reaction of photosynthesis is given in this two steps equation .
Firstly, oxygen in water is oxidized by the light energy:
2H2O → O2 + 4 [H.]
[H.] reduces the carbon in CO2:
4 [H.] + CO2 → (CH2O) + H2O
This reaction occurs together, to yeild overall reaction
CO2 + H2O → (CH2O) +O2
Where [H.], the overall reducing agent
