Hydrogenation reactions are used to add hydrogen across double bonds in hydrocarbons and other organic compounds.
Use average bond energies to calculate DELTA Hrxn for the following hydrogenation reaction:
H2C==CH2(g) + H2(g)-->H3C--CH3(g)
2)Use standard enthalpies of formation to calculate DELTA Hrxn for the following reaction.
CH4(g)+2O(g)--->CO2(g)+2H2O(g)
2H+(aq) + 2Br-(aq) + CO2(g) BrO3-(aq) + 5Br-(aq) + 6H+(aq) Rate = k[Br2] Rate = k[BrO3-][Br-][H+]2 (4th order is RARE!) Exp. What is the rate law? What is the value of the rate constant? Why?
A 50.00-mL sample of white dinner wine required 24.76 mL of 0.03867 M NaOH to achieve a phenolphthalein end point. Express the acidity of the wine in terms of grams of tartaric acid
the activation energy for the reaction involved in the souring of raw milk is 75kj. milk will sour in about 8 hours at 21 degrees c. how long will raw milk last in refrigeratior maintained at 5 degrees c? assume rate constant to be inversely propo..
