To determine change in Gibbs Free Energy, we use the equation
ΔG = ΔG° + RT ln Q
where ΔG is the change in free energy at temperature T
ΔG° is the free energy at standard temperature
R is the universal gas constant
T is the temperature of the system
Q is the reaction quotient
First, we determine the reaction quotient. It is the ratio of the concentration or partial pressure of the products and the reactants. For this case, we do as follow:
<span>P2(g) + 3 Cl2(g) -> 2 PCl3(g)
</span>
<span>Q = P(PCl3) ^2 / (P(P2)(P(Cl2 ^ 3)))
</span>Q = (0.65 atm)^2 / (1.5 atm) (1.6 atm)^3
Q = 0.0688
Substituting to the equation for free energy,
ΔG = ΔG° + RT ln Q
ΔG = -33300 J/mol + (8.314 J/mol-K)(298 K) ln 0.0688
ΔG = -39931.35 J/mol
I think it's <em>80 . 12</em>
pls tell me if correct
It would be 11.265227499999998 of the element beryllium.
<span>The prefix is used to indicate that the main chain of a hydrocarbon contains four carbon atoms is "but-". Examples of carbon compounds with four carbons in the main chain are: butane, butanol, butyl, butene, etc. It can be observed that all of the compounds have a common prefix of "but".</span>
Answer:
0.2320V
Explanation:
Voltage can be defined as the amount of potential energy available (work to be done) per unit charge, to move charges through a conductor.
Voltage can be generated by means other than rubbing certain types of materials against each other.
