Answer:
This is because no energy is being created or destroyed in this system
Explanation:
I think this is correct? I hope it helps.
First, you need to be given the gram formula mass of this molecular or related conditions that can calculate this. Then you need the empirical formula and calculate the gram formula mass of empirical formula. Then use them to get the ratio. Finally you can get the molecular formula.
I think the correct answer from the choices listed above would be the last option. <span>If a decrease in temperature accompanies a reaction, then energy was absorbed which means that the reaction is endothermic. Hope this answers the question. Have a nice day.</span>
Answer:
Explanation:
ΔG° = - 8.03 kJ/mol & ΔG = -45.28 kJ/mol
Thus:
Overall ΔG = (- 8.03 + 45.28) kJ/mol
ΔG = 37.25 kJ/mol
ΔG = 37250 J/mol
Temperature = 27 °C
= (27 + 273)K
= 300 K
Therefore :
ΔG = -RTInK
In K =
In K =
In K =
In K = 14. 93
K =
K =
the standard free energy of the first reaction at 27 °C =
