An uncatalyzed reaction has a rate of 4.2 x 10^-7 sec-1 at 25 degrees Celsius. When an enzyme is added the rate is 3.2 x 10^4 sec-1. Calculate the difference in activation energy between the catalyzed and uncatalyzed reactions. (Please show work so I can see what you did). A. 22 kJ/mol B. 25 kJ/mol C. 43 kJ/mol D. 62 kJ/mol
Hess' Law Enthalpy change for the decomposition of ammonium chloride 1. Write out the reaction NH4Cl(s) -> NH3 (g) + HCl(g) as a series of steps which include the reactions observed in Procedures 2 and 3. Use the known enthalpies for the change of state of NH3 and Hcl, given below. NH3 (g) -> NH3 (aq) (?H = -34,640 J/mol) HCl (g) -> HCl (aq) (?H = -75,140 J/mol) Be sure to show how the reaction steps must proceed so...
