The mean free path (distance travelled between collisions) is the same as before. B. The collision frequency (how often molecules collide with each other) is the same as before. C. The SO2 molecules collide with the walls of the container with less force than before. D. The molecules are moving slower than before. 10. H2S is converted into solid sulfur by the Claus process. The reaction equation for the first step of process is: 2 H2S(g) + 3 O2(8) 2 SO2(8) + 2 H2O(g) for which AH° = -1036 kJ. Which one of following statements about this reaction is incorrect? A. The products are lower in energy than the reactants. B. Raising the temperature of the system will increase the value of Kc. C. The products are more stable than the reactants. D. The bonds in the products are stronger than the bonds in the reactants.

Describe what happens o the average kinetic energy of ideal gas molecules when the conditions are changed as follows: (a) The pressure of the gas is increased by reducing the volume at constant temperature. (b) The pressure of the gas is increased by increasing the temperature at constant volume. (c) The average velocity of the molecules is increased by a factor of 2.
Under which of the following sets of conditions does a real gas behave most like an ideal gas, and for which conditions is a real gas expected to deviate from ideal behavior? Explain. (a) high pressure, small volume (b) high temperature, low pressure (c) low temperature, high pressure
A typical barometric pressure in Redding. California, is about 750 mm Hg. Calculate this pressure in atm and kPa.
A sample of a compound of xenon and fluorine was confined in a bulb with a pressure of 18 tor. Hydrogen was added to the bulb until the pressure was 72 torr. Passage of an electric spark through the mixture produced Xe and HF. After the HF was removed by reaction with solid KOH, the final pressure of xenon and unreacted hydrogen in the bulb was 36 torr. What is the empirical formula of the xenon fluoride in the original sample? (Note: Xenon fluorides contain only one xenon atom per molecule.)
93 The complete combustion of octane can be used as a model for the burning of gasoline: 2C8H18+25O216CO2+18H2O Assuming that this equation provides a reasonable model of the actual combustion process, what volume of air at 1.0 atm and 25°C must be taken into an engine to burn 1 gallon of gasoline? (The partial pressure of oxygen in air is 0.21 atm and the density of liquid octane is 0.70 g/mL.)
