For each part below, use the data below to calculate ΔG at 215 K for each of the following reactions. Then use the data in the c
hart to determine whether each reaction is spontaneous at 215 K.
1 answer:
Answer:
The first reaction is spontaneous
The second reaction is also spontaneous
Explanation:
The question is incomplete or the data part are missing, nonetheless, here is the complete question with the data table ; For each part below , use the data below to calculate ΔG at 215 K for each of the following reactions . Then use the data in the chart to determine whether each reaction is spontaneous at 215 K.
The Gibb's free energy also referred to as the Gibb's function represented with letter G. it is the amount of useful work obtained from a system at constant temperature and pressure. The standard Gibb's free energy on the other hand is a state function represented as ΔG, as it depends on the initial and final states of the system. The spontaneity of a reaction is explained by the standard Gibb's free energy.
If ΔG = -ve ( the reaction is spontaneous)
if ΔG = +ve ( the reaction is non-spontaneous)
if ΔG= 0 ( the reaction is at equilibrium)
Use this hints for any reaction involving the Gibb's free, Enthalpy and entropy.
The step by step calculation with the data table is attached.

Answer:
a) CO₂: <em>21,9%; </em>CO: <em>7,0%; </em>CH₄: <em>18,2%; </em>H₂: <em>0,8%; </em>N₂: <em>52,1%</em>
b) 24,09 g/mol
Explanation:
a) It is posible to obtain the composition of the gas mixture in weight% using molecular mass of each compound, thus:
12% CO₂× = <em>528,1 g</em>
6% CO× = <em>168,1 g</em>
27,3% CH₄× = <em>438,2 g</em>
9,9% H₂× = <em>20,0 g</em>
44,8% N₂× = <em>1254,4 g</em>
The total mass of the gas mixture is:
528,1g + 168,1g + 438,2g + 20,0g + 1254,4g = <em>2408,8 g</em>
Thus composition of the gas mixture in weight% is:
CO₂: ×100 = <em>21,9%</em>
CO: ×100 = <em>7,0%</em>
CH₄: ×100 = <em>18,2%</em>
H₂: ×100 = <em>0,8%</em>
N₂: ×100 = <em>52,1%</em>
b) The average molecular weight of the gas mixture is determined with mole % composition, thus:
0,12×44,01g/mol + 0,06×28,01g/mol + 0,273×16,05g/mol + 0,099×2,02g/mol + 0,448×28g/mol = <em>24,09 g/mol</em>

Answer:
Explanation:
In beta emission, a neutron is converted into a proton thereby reducing the neutron:proton (N/P) ratio.
When a beta emission occurs, the mass number remains the same while the nuclear charge increases by one unit. The daughter nucleus is found one place to the right of its parent in the periodic table.
