The equilibrium conditions for SO2, O2, and SO 3 are important in sulfuric acid production. When a 0.0200 mol sample of SO3 is introduced into an evacuated 1.67 L vessel at 900K, 0.0132 mol SO3 is found to be present at equilibrium. What is the value of Kp for the dissociation of SO3 at this temperature?
the equilibrium constant for a chemical transformation can be predicted from its stoichiometric coefficients whereas the rate law must be determined experimentally.

A certain reaction with an activation energy of 185kj/mol was run at 455k and again at 475 . What is the ratio of f at the higher temperature of f at lower temperature? one significant figure
a solution of 4.00 g of sodium carbonate is mixed with one containing 4.00 g of silver nitrate. after the reaction is complete, the solutions are a mixture of salts.
Describe in 75 words the structure of the carbon atom. What types of bonds does carbon form and why?
A chemist wants to prepare .50 M HCL. Commerical hydorcloric acid is 12.4 M. How many milliliters of the commerical acid does the chemist require to make up 1.50 L of the dilute acid?
Consider the titration of 50.0 mL of 0.200 M HClO4 by 0.100 M NaOH. Calculate the pH after 37.7 mL of NaOH has been added.
Acid Rock Drainage is a common environmental process that releases toxic metals, such as cadmium (Cd2+), and lots of acidity (i.e. H+) into streams and rivers. One strategy to remediate acid mine drainage is to fill the streams with carbonate rock..
Calculate the amount of heat (calories) absorbed when 50.0g of water at 20deg. Celsius spreads over your skin and warms to body temperature, 37deg. celsius.
If the volume of the gas sample is decreased to 15.3 L holding the temp constant, the average molecular speed will increase, decrease or remain the same?
Calculate the molar mass of a Nonelectrolyte that lowers the freezing point of 25.00 g of water to -3.9 degrees C when 4.27g of the substance is dissolved in the water.
