4. a. From the graph, determine the relative reaction rates at 20C and 30C. y=mx+b In ("/time) =-10064 ( 1/29 310) + 30.776 In (fine) = (1/remp/2) th OP 128 Seen on graphs! 01. 081.01 b. For this particular reaction, how good is the rule of thumb that "a 10C increase should double the reaction rate"? Explain your answer. as 2.1 2MP. 0 NO PS 20C as 91.24 2.01 placehold
