Answer:
im pretty sure the correct option here id c
can i please get brainliest
Answer:
C) exothermic
Explanation:
The given reaction is exothermic.
N₂ + 3H₂ → 2NH₃ + ENERGY
when energy is released the reaction is exothermic and when energy is written on left side with reactant it means energy is added and reaction is endothermic.
Exothermic reaction:
The type of reactions in which energy is released are called exothermic reactions.
In this type of reaction energy needed to break the bonds are less than the energy released during the bond formation.
For example:
Chemical equation:
C + O₂ → CO₂
ΔH = -393 Kj/mol
it can be written as,
C + O₂ → CO₂ + 393 Kj/mol
C is correct. Have a good day!
An an increase in
temperature lead to more effective collisions between reactant particles and an
increase in the rate of a chemical reaction because the number of
molecules with sufficient energy to react increases. The answer is number 3.
Iron rusts when exposed to air → chemical property
