5. A certain reaction has a rate law of rate = k[C]. The activation energy for this reaction is 3.0000 x 104 J/mol, and the collision frequency is 2.000 x 10-³. If the desired reaction rate using an initial [C] of 0.0300 M is 1.00 x 10⁹ M/s, what must the reaction temperature be? You must first determine the value of the rate constant k, then use k, EA, and A to determine temperature. Show all work. 6 Find and cito lucing or
