The reaction A+B Products is first order in A, one-half order in B, and has an activation energy of 90 kJ/mol. What is the ratio of the rate of disappearance of A at Condition 2 below to the rate of disappearance of A at Condition 1? Condition 1 T = 300 C CA = 1.5 mol/l CB = 2.0 mol/l Condition 2 T = 350 C CA = 1.0 mol/l CB = 2.5 mol/l
