Answer:
The answer to your question is: True
Explanation:
Gibbs energy is the energy related to a chemical reaction that can be used to do some work.
Gibbs energy is calculated from a reaction and also the spontaneity can be determined.
In a spontaneous reaction Gibbs energy is always negative.
Calcium Carbonate is a type of rock mineral.
Answer:
222.30 L
Explanation:
We'll begin by calculating the number of mole in 100 g of ammonia (NH₃). This can be obtained as follow:
Mass of NH₃ = 100 g
Molar mass of NH₃ = 14 + (3×1)
= 14 + 3
= 17 g/mol
Mole of NH₃ =?
Mole = mass /molar mass
Mole of NH₃ = 100 / 17
Mole of NH₃ = 5.88 moles
Next, we shall determine the number of mole of Hydrogen needed to produce 5.88 moles of NH₃. This can be obtained as follow:
N₂ + 3H₂ —> 2NH₃
From the balanced equation above,
3 moles of H₂ reacted to produce 2 moles NH₃.
Therefore, Xmol of H₂ is required to p 5.88 moles of NH₃ i.e
Xmol of H₂ = (3 × 5.88)/2
Xmol of H₂ = 8.82 moles
Finally, we shall determine the volume (in litre) of Hydrogen needed to produce 100 g (i.e 5.88 moles) of NH₃. This can be obtained as follow:
Pressure (P) = 95 KPa
Temperature (T) = 15 °C = 15 + 273 = 288 K
Number of mole of H₂ (n) = 8.82 moles
Gas constant (R) = 8.314 KPa.L/Kmol
Volume (V) =?
PV = nRT
95 × V = 8.82 × 8.314 × 288
95 × V = 21118.89024
Divide both side by 95
V = 21118.89024 / 95
V = 222.30 L
Thus the volume of Hydrogen needed for the reaction is 222.30 L
Overvoltage influence the products in the electrolysis of aqueous salts by affecting the solvation effects, polarization of electrode, and also affect the formation of gaseous products.
<h3>What is electrolysis? </h3>
It is defined as a process which leads to the chemical change when an electric current is allow to pass through an electrolyte.
During the electrolysis process,the positively charged electrode gains the electrons and undergoes the reduction process while the negatively charged electrode loses the electrons , undergoes oxidation.
When two half reaction are possible at an electrode, one with the other which is more positive electrode potential occur. For the gases to be produced at electrodes, an additional voltage is required. This is termed as overvoltage.
The overvoltage affects the solvation effects, polarization of electrode, and also affect the formation of gaseous products.
