Over the time interval 300 to 400 seconds, the rate of reaction with respect to A is delta[A]/delta t =3.7 x 10^-5M/s. Over the same time interval what is the rate of reaction with respect to B, delta[B]/delta t? A) delta [b]/delta t = 3.7 x 10^-5 B) delta [b]/delta t = (1/4)(delta[a]/delta t) = (1/4)(3.7 x 10^-5M/s) =9.2 x 10^-6 M/s C)delta [b]/delta t = (1/2)(delta[a]/delta t) = (1/2)(3.7 x 10^-5M/s)=1.8X10^-5 D)delta [b]/delta t = -(1/2)(delta[a]/delta t) = -(1/2)(3.7 x 10^-5M/s)=-1.8X10^-5
