What Size container do you need to hold 0.0459 mol of N2 gas at stp

Allushta [10]

Hello!

You need to calculate the volume of the container. To calculate the volume of this amount of N₂ gas we need to make the assumption that N₂ behaves like an ideal gas.

1 mole of an ideal gas under Standard Temperature and Pressure occupies 22,4 L so the calculations are as follows:

$0,0459 mol N_2* \frac{22,4 L}{1 mol N_2}= 1,028 L$

So, the volume of the container should be 1,028 L or more.

Have a nice day!

Using relative enthalpy and entropy values, determine how the process is affected after each of the following temperature or pre

lutik1710 [3]

The question is incomplete, the complete question is:

Using relative enthalpy and entropy values, determine how the process is affected after each of the following temperature or pressure changes? Consider that a more effective reaction produces more product or more product in a shorter amount of time.

Reaction: SO2 (g) + 2H2S (g) ↔ 3S(s) + 2H2O (g)

Substance | ΔG kJ/mol | ΔH kJ/mol

H2O(g) | -228.6 | -241.8

H2O(l) | -237.1 | -285.8

SO2(g) | -300.4 | -296.9

SO3(g) | -370.4 | -395.2

H2S(g) | -33.01 | -20.17

S(s) | 0 | 0

- Temp. decreases while maintaining container size

- Temp. increases while maintaining container size

- Pressure decreases while maintaining container size

- Pressure increases while maintaining container size

Answer:

Explanation:

ΔH∘rxn=ΔH∘f(products)−ΔH∘f(reactants)

ΔH∘rxn= [0+2(-241.8)] - [(-296.9) + 2(-20.7)]= -145.6KJ/mol

ΔG∘rxn=[(0+ 2(-228.6) -[(-300.4) + 2(-33.01)]= -90.78KJ/mol

The reaction is spontaneous since ΔG∘rxn is negative

The reaction is exothermic since ΔH∘rxn= negative

1) increase in pressure is less effective because it favours the reverse reaction.

2) increase in temperature is less effective since it favours the reverse reaction given that the reaction is exothermic in nature

3) decrease in pressure is more effective, it favours the forward reaction

4)Decrease in temperature is more effective because it favours the forward reaction.
