The mass of 2.47 moles of fluorine atom is 46.9 g
calculation
mass of Fluorine= moles x molar mass
moles = 2.47 moles
molar mass of fluorine = 18.998 g/mol
mass is therefore= 2.47 moles x 18.008 g/mol = 46.9 g
Answer:
No, it is not feasible because the Gibbs free energy change is positive
Explanation:
∆Hreaction= (-602 KJ/mol) - (-348 KJ/mol) = -254 KJ/mol
∆Sreaction = (42 + 27) J/Kmol - (33 + 44) J/K = -8J/Kmol
From;
∆G = ∆H - T∆S
∆G = 254 × 10^3 J/mol - [340K × (-8 J/Kmol)]
∆G = 2.57 × 10^5 J/mol
Note that when the change in free energy is positive, a reaction is non spontaneous. Only a reaction that has a negative change in free energy is spontaneous.
