2 \# 2. The following observations were made for the rate of formation of compound B: (i) It appears to be 2nd order in A (ii) When the concentration of C is low, it appears to be 1st order in C (iii) Conversely, at high concentration of C, it appears to be 0th order in C (iv) Concentration of B does not appear to affect the rate The following mechanism is proposed for the reaction: A+Ak1kIAAAAk2k2BB+CC+AAk3B Derive the expression for the above rxn mechanism. Under what constraints would this rate expression approximate the observed behavior
