Answer:
inhibitor :)
Explanation:
Catalysts speed the reaction up, and the other 2 are essential for the reaction to work, so an inhibitor :)
A tree is able to speed up erosion because it break up rocks. This can happen as it’s roots grow through rocks, the water breaks through rocks, etc.
It can slow erosion down because it can act as a barrier to the elements that erode.
Answer:
The forward reaction is an exothermic reaction.
Explanation:
An exothermic reaction is one in which energy is released, usually in the form of heat hence the enthalpy of the reaction is negative. When a reaction exothermic, the energy of the reactants is greater than the energy of the products hence the excess energy is given out as heat. The reactants lie at a higher energy level in the reaction profile compared to the products.
When we look at the reaction given in the question, NO(g) ⇌ 12N2(g) + 12O2(g) ΔH = −90.3 kJ , we can easily see from the thermochemical reaction that the forward reaction is exothermic, energy is released by the reaction system as evidenced by the negative enthalpy of reaction.
