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:
Moore's Law
Explanation:
An observation that the number of transistors in a dense integrated circuit doubles about every two years (24 months), was made by Gordon E. Moore, the co-founder of Intel, and this observation became Moore's Law in 1965.
Therefore, Moore's Law is based on the observation that the rate of increase in transistor density on microchips had increased steadily, roughly doubling every 18 to 24 months.
Answer:
33.4KW
Explanation:
Firstly, we calculate the power index in a reversible heat engine which is given as;
n = 1 - T1/T2
T1 = atmospheric temperature 298k
T2 = reservoir temperature 1500k
n = 1 - 298/1500
n = 0.8013
output energy = n × energy input
0.8013×150000 = 120195KJ/hr
Power output = 120195KJ/hr/3600 = 33.4KW

Answer:
Small businesses contribute to local economies by bringing growth and innovation to the community in which the business is established. Small businesses also help stimulate economic growth by providing employment opportunities to people who may not be employable by larger corporations.
