SO2 (5.00 g) and CO2 (5.00 g) are placed in a 750.0 ml container at 50.0 °C. the partial pressure of SO2 in the container was 2.762 atm.

<h3>Further explanation </h3>

To calculate the partial pressure, we can calulate the total pressure

Total pressure =  \frac{nRT}{V} SO2  + \frac{nRT}{V} CO2

Where:

  • n is the number of moles
  • R is the general gas constant = 0.0821 L.atm/K.mole
  • T is the temperature in Kelvin
  • V is the total volume

The amount of SO2 is n SO2 = mass/molar mass = m/M = \frac{5 }{32} + 16*2 = 0.078125 mol

The amount of CO2 is n CO2 = mass/molar mass = m/M = \frac{5}{14} + 16*2 = 0.1 mol

Total amount of gas is n(total) = n1 + n2 = 0.078 + 0.113 = 0.191  mol

T = 50+273 = 323 K

V = \frac{750}{1000} = 0.75liters

Total Pressure  p*V = n*R*T

Total Pressure = (0.078125*0.0821*\frac{323}{0.75} ) + (0.1*0.0821*\frac{323}{0.75}) = 2.7623 + 3.535 = 6.298 atm

Partial pressure = x SO2 * Total Pressure = (\frac{no. of moles of SO2 }{total no. of moles} ) * Total pressure = (\frac{0.078125}{0.078125} +0.1) * 6.298 = 2.762atm

To calculate the partial pressure, we have to calulate the total pressure first.
Total pressure = (nRT/V)SO2 + (nRT/V)CO2
n is the number of moles
R is the general gas constant = 0.0821 L.atm/K.mole
T is the temperature in Kelvin
V is the total volume
n SO2 = mass/molar mass = 5/ 32 + 16*2 = 0.078125
n CO2 = mass/molar mass = 5/14+ 16*2 = 0.1
T = 50+273 = 323K
V = 750/1000 = 0.75 liters
Total Pressure = (0.078125*0.0821*323/0.75) + (0.1*0.0821*323/0.75) = 2.7623 + 3.535 = 6.298 atm
Partial pressure = x SO2 * Total Pressure = (no. of moles of SO2 / total no. of moles) * Total pressure = (0.078125/0.078125+0.1) * 6.298 = 2.762 atm.

A reaction is non-spontaneous at any temperature when
slavikrds [6]

Answer:

A reaction is non-spontaneous at any temperature when the Gibbs free energy > 0.

Explanation:

There is a state function, that determines if a reaction is sponaneous or non spontaneous:

ΔG = Gibbs free energy

A reaction is non spontaneous when it does require energy to produce that reaction. It will be spontaneous, when the reaction does not require energy to be occured.

The formula is: ΔG = ΔH - T.ΔS

ΔH → Enthalpy → Energy gained or realeased as heat.

ΔH < 0 → <em>Exothermic reaction. Spontaneity is favored </em>

T  → Temperature

ΔS → Entropy →  Degree of disorder of a system.

When the system has a considered disorder ΔS > 0, disorder increases.

When the system is more ordered, ΔS < 0, disorder decreases.

The reaction will be non spontaneous if, the enthalpy is positive (endothermic reaction) and the ΔS < 0 (disorder decreases). It will not occur if we do not give energy.

ΔG < 0 → Spontaneous reaction

ΔG > 0 → Non spontaneous reaction

ΔG = 0 → System in equilibrium
