Explanation:
Transfer of mass A into stagnant film B depends on the availability of driving force.
Whereas driving force is the pressure difference at the surface of A and the bulk.
As, 
Therefore, putting the given values into the above formula as follows.
= 
= 0.132 
Thus, we can conclude that the flux of A from a surface into a mixture of A and B is 0.132
ΔS = 0.250 J·K^(-1)
<em>Step 1</em>. Calculate the <em>moles of CO</em>
From the<em> </em><em>Ideal Gas Law</em>,
<em>n</em> = (<em>pV</em>)/(<em>RT</em>) = (8.00 kPa × 3.00 L)/(8.314 kPa·L·K^(-1)·mol^(-1) × 298.15 K)
= <em>0.009 682 mo</em>l
Δ<em>S</em> = <em>nC</em>_Vln(<em>T</em>_2/<em>T</em>1)
= 0.0096 82 mol × 20.17 J·K^(-1)mol^(-1) ln(1073.15 K/298.15 K)
= 0.1953 J·K^(-1) × ln3.599 = 0.250 J·K^(-1)
Answer:
2621.75 j heat is required to increase the temperature 25.5°C to 46°C.
Explanation:
Given data:
Mass of sample = 142.1 g
Initial temperature = 25.5°C
Final temperature = 46°C
Specific heat capacity of Al = 0.90 J/g.°C
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 46°C - 25.5°C
ΔT = 20.5°C
Q = 142.1 × 0.90 J/g.°C × 20.5°C
Q = 2621.75 j
Thus, 2621.75 j heat is required to increase the temperature 25.5°C to 46°C.
