Homework Answers
a)
rate = -(1/2)d[H2]/dt
rate = - d[O2]/dt
rate = (1/2)d[H2O]/dt
b)
we have,
rate = - d[O2]/dt = (1/2)d[H2O]/dt
- d[O2]/dt = (1/2)d[H2O]/dt
- (-0.23 mol/L.s) = (1/2)*d[H2O]/dt
d[H2O]/dt = 0.46 mol/L.s
Answer:
H2O is increasing at the rate of 0.46 mol/L.s

Ammonia has been studied as an alternative "clean" fuel for internal combustion engines, since its reaction with oxygen produces only nitrogen and water vapor and in the liquid form it is easily transported. An industrial chemist studying this reaction fills a 25.0 L tank with 1.4 mol of ammonia gas and 1.6 mol of oxygen t 37.0°C. He then raises the temperature, and when the mixture has come to equilibrium measures the amount of water vapor to be 1.3 mol....

1) Nitrogen monoxide gas reacts with hydrogen gas to form ammonia gas and water vapor. This reaction is reversible (can go forward and reverse). If the temperature is held constant for this reaction, predict the direction the equilibrium will shift given the following changes given below and provide a brief explanation of why it will go in the direction you indicated: (a) Removing hydrogen gas (b) Adding nitrogen monoxide gas (c) Adding water vapor (d) Removing ammonia gas (e) Increasing...

Hydrogen and oxygen gases are utilized as reactants for fuel cells. Hydrogen gas is oxid side to generate protons and electrons which move to the cathode side to react with oxygen to produce electricity and water as byproduct. Molecular weight: M(H2) -2 g/mol, M(O)-32 g/mol, M(H-0) - 18 g/mol.

A natural gas containing 82 mole% CH, and the balance C2H6 is used as a fuel to generate steam in an industrial plant (Figure 2). The natural gas is fed into a furnace at 25°C and burned at a rate of 10.000 mol/hr with 20% excess air. The heat transferred from the furnace is used to convert a liquid feed water at 25 °C into a saturated steam at 30 bar. During the combustion of natural gas, all the CH,...

Quantitative: In the 1950s liquid hydrogen was considered as a fuel for a new type of aircraft being developed, the SR-71 Blackbird (shown in Figure 1). Figure 1: The SR-71 Blackbird Early research on the project focused on which fuel to use for the Blackbird. Pratt & Whitney had a J-57 engine that was designed for kerosene and being considered for implementation on the Blackbird. The J-57 only took 5 months to convert to running on liquid hydrogen, however tests...
