Question- A gas was collected over water by bubbling it into an inverted flask at 27.0 degrees C. If the gas was collected at 760torr, what is the actual pressure of the gas
What mass (in grams) of CH4 is contained in a 555 mL volume at a pressure of 760.0 torr, and at a temperature of 400.0 K?
The rate of a reaction increases with increasing concentrations of reactants because you have more collisions occurring in a given time period. The rate of a chemical reaction is inversely proportional to the temperature.
Calculate the pressure and the temperature of the compressed gas. In a diesel engine the compression ratios are typically much higher; redo the same calculation for the compression ratio of 20:1.
