A catalyst decreases the activation energy of a given reaction by exactly 15 kJ/mol. By what factor does the reaction rate increase at 25oC when the catalyst is used? Assume that the Arrhenius pre-exponential factor, A, is the same for the catalyzed and uncatalyzed reactions.
A solution is created by adding 0.05 moles of H2CO3 (3.1 g, total mass) to 5-L of water, resulting in a pH of 4.2. Now, we add sodium hydroxide (NaOH, strong base) until the pH reaches 10. You can neglect any changes in volume. What is the alkalin..
The mass spectrum of an organic compound shows the relative abundances of M to be 83.79% and M 1 to be 13.59%. Assuming the peaks are caused by 12C and 13C isotopes,
A tightly sealed 5.0 L flask contains argon at 85.2 deg. C and 781 mm Hg. The flask is heated until the pressure is doubled. What it the temperature of the gas
Bromothymol blue is a common acid-base indicator. It has a Ka equal to 1.6 X 10^-7. Its unionized form is yellow and its conjugate base is blue. What color would a solution have at pH=5.8?
Given the following thermochemical equation, calculate the heat (in kJ) involved in decomposing 18.0 g of water to give one mole of (g). 2H2 + O2 ---> 2H2O change in heat is -571.6 Kilojoules a. 286 b. 572 c. 1143 d. -572 e. -286
When the epoxide 2-vinyloxirane reacts with lithium dibutylcuprate, followed by protonolysis, a compound A is the major product formed. Oxidation of A with PCC yields B, a compound that gives a positive Tollens test and has an intense UV absorptio..
why does a salt containing a cation from a weak base and an anion from a strong acid form an acidic solution
A 75.0 L steel tank at 20.0C contains acetylene gas (C2H2) at a pressure of 1.39 atm. Assuming ideal gas behavior, how many grams of acetylene are in the tank?
Explain why cis dichloroethene has a boiling point of 60 degrees C while trans - dichloroethen has a boiling point of 48 degrees C.
Calculate the number of oxygen molecules per liter of air if the temperature and pressure were 25°C and 1.00 atm, respectively.
Bond length is the distance between the centers of two bonded atoms. On the potential energy curve, the bond length is the internuclear distance between the two atoms when the potential energy of the system reaches its lowest value.
A certain gaseous oxide of sulfur has an effusion rate that is 0.707 times the effusion rate of oxygen gas
