(About Ads) This is question #6 from Chemistry Test 3 QVAULTDAT: Determine the numerical value of the rate constant for the reaction A+B-->C from the experimental data given below. E [A] [B] Rate 1 .45 .26 1.00 2 .90 .26 1.05 3 .90 .52 2.03 A) k=(0.26)(0.45) B) k=0.26 C) k=(0.26)^2(0.45) D) k=(0.26)(0.25)^2 E) k=(0.31)^3(0.25) How is the correct answer B??? I keep getting K = 1/.26 = 4 since R=K[B]. Does anyone know why B is the correct answer?

I also agree with this analysis.
