1. (8 pts) Virtually every pchem textbook has a table of enthalpy values for 25°C. One use for these may be to calculate the enthalpy fora phase change such as boiling. However, not t0o many compounds boil at 25°C. You are going to calculate the percent difference between the heat of vaporization of ethanol using data for 25°C and that at its boiling point of 78°C. a) Write the chemical equation that shows the vaporization of 1 mol of ethanol...

only questions number: #3,6,8,16,19,22 Δι CH 122 - Practice Problems for Chapter 12 Do NOT use this problem set solely as test preparation. This problem set does NOT cover everything that we have discussed in class. You will still need to study class materials in order to do well on the learning assessment. 1. Of the following all are valid units for a reaction rate except A. moll B. M/S C. molhr D.g's E.molle 2. Which one of the following...
rates of chemical reactions Plz help!! how do I find specific rate constant k, 1/T, In K thank you Rates of Chemical Reactions: Report Form Rate Law Summary: (a) From your measurements, what are the reaction orders with respect to each of the three reactants H;O; HOO (b) What is the rate expression (rate law) for the uncatalyzed reaction? Rate = K LT-] [H202) (c) What is the total reaction order? 2 3. Effect of Temperature on the Reaction Rate...
