Answer:
Attached below
Explanation:
Free energy of mixing = ΔGmix = Gf - Gi
attached below is the required derivation of the
<u>a) Molar Gibbs energy of mixing</u>
ΔGmix = Gf - Gi
hence : ΔGmix = ∩RT ( X1 In X1 + X2 In X2 + X3 In X3 + ------- )
<u>b) molar excess Gibbs energy of mixing</u>
Ni = chemical potential of gas
fi = Fugacity
N°i = Chemical potential of gas when Fugacity = 1
ΔG = RT In ( a2 / a1 )
Answer:
92.0 torr/min.
Explanation:
- For the reaction: <em>2NO(g) + Cl₂(g) → 2NOCl(g).</em>
∵ The rate of the reaction = - 1/2(ΔP)NO/Δt = - (ΔP)Cl₂/Δt = 1/2(ΔP)NOCl/Δt.
∵ (ΔP)NO/Δt = - 184 torr/min.
<em>∴ The rate of change of the total pressure in the vessel = - 1/2(ΔP)NO/Δt</em> = (- 1/2)(- 184 torr/min) = <em>92.0 torr/min.</em>
False. They usually give away their electrons to form ionic bonds
Carbon-13 and Carbon-14 are isotopes of the element carbon. All carbon atoms have 6 protons in their nucleus and most have 6 neutrons. Since the mass number consists of # of protons + # of neutrons, Carbon 12 has an atomic mass of 12 ( = 6 protons + 6 neutrons). Carbon-13 atoms have one extra neutron, giving it a total of 7 neutrons. Carbon-14 atoms have two extra neutrons, giving them a total of 8 neutrons. Therefore the mass number of C-12= 12, C-13= 13 and C-14= 14.
