How many times faster will the reaction occur
Assume that the activation energy for a certain reaction is 173 kJ/mol and the reaction is started with equal initial concentrations of reactants. How many times faster will the reaction occur at 40 degrees Celsius than at 10 degrees Celsius?

A solution of H2SO4 with unknownconcentration was titrated with the standard base with .0233Molarity. A volume of 5.03mL of the acid solution required 12.07mLof the standard base to reach the end point using phenolphthaleinindicatior.
An "ice calorimeter" can be used to determine the specific heat ofa metal. A piece of hot metal is dropped into a weighed quantity ofice. The quantity of heat transferred from the metal to the ice canbe determined from the amount of ice melted.
Write the mass action expression for the reaction ofaqueous solutions of Fe(NO3)3 and NaNCS in equimolarquantities.
Neglecting air resistance (not a good idea if you are the batter), find how far the ball drops because of gravity by the time it reaches home plate.
One reason carbon monoxide (CO) is toxic is that it binds to the protein hemoglobin more strongly than oxygen does. The bond between hemoglobin and CO absorbs radiation of 1953^-1. (Theunits are the reciprocal of the wavelength in centimeters.)
A mixture of carbon and sulphur has a mass of 9.0 g. Complete combustion with excess oxygen gives 23.3 g of a mixture of carbon dioxide and sulphur dioxide. Find the mass of sulphur in the original mixture.
What range is characteristic of weak acids? Why is there a correlation between electrostatic potential and acidstrength?
The electron affinity of nitrogen is a +7 while those for carbon and oxygen are !122 and !141 kJ/mole, respectively. Why is it even reasonable to suggest nitrogen having a positive electron affinity with carbon and oxygen have negative electron af
The rates of dehydration for cis-2-methylcyclohexanol and trans-2-methylcyclohexanol were determined. The rate of dehydration of the cis isomer relative to the trans isomer was found to be 30:1.
What mass of KClO3 will produce 48.00 g of O2 if the decomposition of KClO3 is complete? (The answer is 122.5) Can you explain how to get to this answer?
