If 3 moles of a compound use 12 J of energy in a reaction, what is the Hreaction in kJ/mol
1 answer:
Answer:
Explanation:
Hello,
In this case, the molar enthalpy of reaction is obtained by dividing the involved energy by the reacting moles:
Thus, it is important to notice that the compound "uses" the energy, it means that it absorbs the energy, for that reason the sign is positive. Moreover, computing the result in kJ/mol we finally obtain:

Answer:
Up to
.
Explanation:
The equation for this reaction: is indeed balanced.
Notice that the coefficient of is
while that of
is
.
Therefore, each unit of this reaction would consume units of
while producing
units of
. In other words, this reaction would produce three times as much
as it consumes
.
If all that of
molecules are actually consumed through this reaction, three times as many
molecules would be produced. That corresponds to
of
molecules.
