Steam reforming of methane ( CH4 ) produces "synthesis gas," a mixture of carbon monoxide gas and hydrogen gas, which is the starting point for many important industrial chemical syntheses. An industrial chemist studying this reaction fills a 1.5 L flask with 0.60 atm of methane gas and 2.6 atm of water vapor at 47. °C. He then raises the temperature, and when the mixture has come to equilibrium measures the partial pressure of hydrogen gas to be 1.4 atm. Calculate the pressure equilibrium constant for the steam reforming of methane at the final temperature of the mixture. Round your answer to 2 significant digits x10.

The pressure equilibrium constant for the reaction is

Explanation:

We are given:

Initial partial pressure of methane = 0.60 atm

Initial partial pressure of water vapor = 2.6 atm

Equilibrium partial pressure of hydrogen gas = 1.4 atm

The chemical equation for the reaction of methane gas and water vapor follows:

Initial:             0.60    2.6

At eqllm:       0.60-x  2.6-x     x       3x

Evaluating the value of 'x':

So, equilibrium partial pressure of methane gas = (0.60 - x) = [0.60 - 0.467] = 0.133 atm

Equilibrium partial pressure of water vapor = (2.6 - x) = [2.6 - 0.467] = 2.133 atm

Equilibrium partial pressure of carbon monoxide gas = x = 0.467 atm

The expression of for above equation follows:

Putting values in above equation, we get:

Hence, the pressure equilibrium constant for the reaction is

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j
