Please help me answer all questions. I will give a thumbs up if all questions are answered.

This is a multiple-choice test consisting of 35 questions. Each correct answer is worth three points for a total of 105 points. Mark all answers on your 882-scantron form. the scantron will be graded 1. Given the initial rate data for the reaction A + B C, determine the rate equation for the reaction. 0.020 0.020 0.060 0.030 0.060 0.030 0.010 0.040 0.090 a) rate- kIA[B] b) rate- k[A][B] c) rate-k[A[B] d) rate k[A B] e) rate k[A[B] 2. A solution is made by dissolving 10.0 g of ethylene glycol (C HeO, molar mass 62.0 g/mol) in 75.0 g of water. At what temperature will this solution freeze? (The K of water is 1.86°C/m and pure water freezes at o°C.) a) -3.53°C b) -4.00°C c)-1.24°C d) -2.15°C e) -0.300°C 3. The first-order rate constant for the following reaction is 8.5 x 103s 2N20s(g) 4NO2(8) + Ox(g) If the initial concentration of N20s is after 60.0 sec? .500 M, then what is the No0s concentration a) 0.0626 M b) 0.398 M c) 0.833 M d) 0.444 M e) 0.300 M
