23.) What is the concentration of a reactant after 22.0 s if the initial concentration is 0.150 M and the rate constant is 5.4 x 10ā»Ā² sā»Ā¹?
32.) The activation energy, Ea, for a particular reaction is 13.6 kJ/mol. If the rate constant at 475 K is 0.0450 1/min, then what is the value of the rate constant at 701 K? (R = 8.314 J/mol ā¢ K) Show all work, answer both thank you!! Write neatly.
