Question 17 (4 points) Listen ► The rate constant, k, for a reaction is 0.0354 sec¹ at 40°C. Calculate the rate constant for the same reaction at 125°C if the activation energy is 26.5 kJ/mol. 01.20 Onone of the choices O2.00 0.312 0.0768
Question 16 (2 points) Listen The mechanism of a reaction is believed to be the following: 1. NO2 + NO2 → NO3 + NO (slow) 2. NO3 + CO NO₂ + CO₂ (fast) The rate law for the overall reaction is O Rate = k [NO₂]² O Rate = k [NO3][CO] O Rate k [NO₂] = Rate = k [NO₂] [CO] Onone of the choices
