Answer #1

i think there is a mistake in first rate of reaction. I hope it suppossed to come 0.0159

R = k [A1]x [B]y

r3/r2 = 0.9/0.3 = 0.0476/0.0159

           = [3]y = [3]1

y = 1 [first order with respect to B]

r2/r1 = 0.3/0.15 = 0.0159/0.0159

              = [2]x = [1]1

                   x= 0 (zero order with respect to A)

Rate law = k [B]
