For a van der Waals gas, use the thermodynamic equation of state to find [dU/ dV]T. Compare your result to the corresponding value of the same derivative for an ideal gas. Explain the difference.
How many ml of 0.122 M MnO4- are required to react with an excess of C2O4^2- in order to produce 75.25 ml of carbon dioxide gas measured at 30.0 degrees C and 715 torr? MnO4- (aq) + C2O4^2- (aq) -------> MnO2 (s) + CO2 (g) Basic solution
A bicycle tire is filled with air to a pressure of 100. psi at a temperature of 19 degrees celcius. Riding the bike on asphalt on a hot day increases the temperature of the tire to 58 degrees celcius.
The rate expression for a particular reaction is rate=k[A][B]^2. If the initial concentration of B is increased from 0.1M to 0.3M, the initial rate will increase by which of the following factors
