A reaction in which and react to form products is zero order in , one-half order in , and second order in .By what factor does the reaction rate change if is doubled (and the other reactant concentrations are held constant)
The air in a 5.00-L tank has a pressure of 1.20 atm. What is the new pressure, in atm, of the air when the air is placed in tanks that have the following volumes if there is no change in temperature? a) 1.00 L. b) 2500. mL. c) 750. mL. d) 8.0 L.
Determine ΔSsys separately for the volume and temperature changes and show that ΔSsys=0 for a reversible adiabatic process. Also, if the expansion had instead occurred irreversibly against a constant external pressure of 1 atm
It is given that the v.p. of water =233.7 mm Hg.at 70 degree Celsius then calculate the vapor pressure? express your answer in mm Hg ?
The value of Kc for this reaction is 5.0 at 600 K. What are the equillibrum partial pressures of the three gases if a reaction vassel initially contains a mixture of the reactants in which Pco=Pcl2=0.215 atm and Pcocl2= 0.000 atm?
Determine the freezing point (°C) of a 0.015 molal aqueous solution of MgSO4. Assume i = 2.0 for MgSO4. The molal freezing-point-depression constant of water is 1.86 °C/m..

Iron (III) oxide(s) is heated in excess carbon monoxide(g) to form iron(s) and carbon dioxide(g). If the percent yield of iron was 83.0% and the actual yield was 9.87 g, how much iron (iii) oxide was used?
calculate the number of microstates, W, that have this energy. Make sketches of these microstates. Calculate the corresponding entropy for each state.
Carbon-11 radioactively decays by positron emission with a half-life of 20.4 minutes. If a dosage of carbon-11 is administered to a patient for a PET scan, what percentage of carbon-11 will remain in the patient's system after 61.2 min
The total pressure of a mixture of gases is: dependent only upon the pressure of the gas which is present to the greatest extent. obtained by multiplying the individual pressures by the number of moles and averaging.
A beaker with 120 mL of an acetic acid buffer with a pH of 5.00 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M. A student adds 5.50 mL of a 0.250 M HCl solution to the beaker. How much will the pH..
