Answer:
Explanation:
a) for shifting reactions,
Kps = ph2 pco2/pcoph20
=[h2] [co2]/[co] [h2o]
h2 + co2 + h2O + co + c3H8 = 1
it implies that
H2 + 0.09 + H2O + 0.08 + 0.05 = 1
solving the system of equation yields
H2 = 0.5308,
H2O = 0.2942
B) according to Le chatelain's principle for a slightly exothermic reaction, an increase in temperature favors the reverse reaction producing less hydrogen. As a result, concentration of hydrogen in the reformation decreases with an increasing temperature.
c) to calculate the maximum hydrogen yield , both reaction must be complete
C3H8 + 3H2O ⇒ 3CO + 7H2( REFORMING)
CO + H2O ⇒ CO2 + H2 ( SHIFTING)
C3H8 + 6H2O ⇒ 3CO2 + 10 H2 ( OVER ALL)
SO,
Maximum hydrogen yield
= 10mol h2/3 molco2 + 10molh2
= 0.77
⇒ 77%
Answer:
39⁰
Explanation:
We have cohesion c = 25kpa
Then the normal stress = 39kpa
Shear stress = 56kpa
This question is asking us to find the angle of internal friction
Shear stress at the time of failure = cohesion C + normal stresstanΦ
56 = 25 + 39tanΦ
Φ = angle if refractive index
Φ = 38.48⁰
This is approximately 39⁰
Therefore in answer to this question, the angle of internal friction for the soil is nearly 39⁰
