Initials: ________8.A. Use Hess’s Law and ∆Hfvalues to determine the enthalpy change, ∆H, for the following reaction: (3M)C2H4(g)+3 O2(g)2 CO2(g)+2 H2OB. Rewrite the reaction from part A and include the energy term in the reaction:(1M)(l)____________________________________________________________________________________C. Write the Formation reaction to make H2O(l): ___________________________________________ (1M)9.A. Sodium hydroxide is an active ingredient in some brands of drain cleaners.Calculate the molar enthalpy ofsolution, ∆Hsol,for NaOH if 4.00 g of NaOH are dissolved in 200.0 ml of water in a coffee cup calorimeter andthe temperature of the water increases from 18.0oC to 23.3oC.(3M)B. Is this reaction exothermic or endothermic? ______________________________ (1 M)C. Calculate the enthalpy change, ∆H, if 3.0 mol of NaOH was dissolved in water. (1 M)10.The initial rate of the reaction: 2 NO(g)+ Cl2(g)→ 2 NOCl(g)has been measured at the reactant concentrationsshown (in mol/L).Experiment[NO][Cl2]Initial rate (mol/(L·s))10.100.100.1820.100.200.3630.200.201.44A.Determine the rate law equation: (2M)B.Determine the rate constant, K: (2M)C.According to these results, what would be the initial rate if both concentrations are:[NO] = [Cl2] =0.30 mol/L?(1M)
Initials: ________11.Given the following reaction mechanism:Step 1:2NO2+O22NO3(slow)Step 2:2 NO3+O22 NO4(fast)A.Identify any Catalysts: ____________________________________ ORReaction Intermediates: ____________________________________________ (2M)B.Write the overall reaction: __________________________________________________________ (1M)C.Write the rate law equation: __________________________________ (1M)D.What is the overall order of this reaction? ________(1M)12.The rate at which a reaction proceeds can be affected by a number of different factors.For the followingreaction,Zn(s)+ 2 HCl(aq)ZnCl2(aq)+ H2(g), explain 5 different changes that could be made to this specificreaction which would INCREASE the rate of the reaction and explainWHY.You may substitute Zn for adifferent metal for one of your changes.
