For the reaction: ch3oh(g) ⇌ co(g) + 2h2(g), with the equilibrium concentrations for [ch3oh]=0.20 m, [co]=0.44 m, and [h2]=2.7 m

, determine the gas phase equilibrium constant (kp) at 400 0c?

The concentration equilibrium constant is calculated as:
Kc = [CO][H2]^2 / [CH3OH] = (0.44 M)(2.7 M)^2 / (0.20 M) = 16.038 M^2
The degree of the reaction is the sum of the product coefficients minus that of the reactants: n = 1 (CO) + 2 (H2) - 1 (CH3OH) = 2
Then the pressure equilibrium constant is calculated as:
Kp = Kc*(RT)^(n) = (16.038 M^2)*[(0.08206 atm/M-K)(673.15 K)]^(2) = 48,936.95 atm^2
Remember to use absolute temperature of 400+273.15 K, not the 400 C itself.

1. Meteorologist predict the weather by using tools. They use these tools to measure atmospheric conditions that occurred in the past and present, and they apply this information to create educated guesses about the future weather. The best we can do is observe past and present atmospheric patterns and data, and apply this information to what we think will happen in the future. Meteorologists use the scientific method on a daily – and even hourly – basis!

2. They use thermometers, barometers, sling psychrometers and rain gauges. They also use anemometers, hygrometers, weather maps, weather balloons and weather satellites.

Sulfur and oxygen form both sulfur dioxide and sulfur trioxide. When samples of these are decomposed, the sulfur dioxide produce
Diano4ka-milaya [45]
To determine the mass of oxygen per gram of sulfur for sulfur dioxide, we simply obtain the ratio of the mass of oxygen and the mass of sulfur produced from the decomposition of sulfur dioxide. All other values given in the problem statement above are just to confuse us that the question is a difficult one. We do as follows:

mass of oxygen per gram sulfur = 3.45 g / 3.46 g
mass of oxygen per gram sulfur = 0.9971 g O2 / g S
