For the reaction A+B+C→D+EA+B+C→D+E, the initial reaction ratewas measured for various initial concentrations of reactants. Thefollowing data were collected:
| Trial | [A][A]
(MM) | [B][B]
(MM) | [C][C]
(MM) | Initial rate
(M/sM/s) |
| 1 | 0.30 | 0.30 | 0.30 | 9.0×10−5 |
| 2 | 0.30 | 0.30 | 0.90 | 2.7×10−4 |
| 3 | 0.60 | 0.30 | 0.30 | 3.6×10−4 |
| 4 | 0.60 | 0.60 | 0.30 | 3.6×10−4 |
Rate law equation
The rate of a chemical reaction depends on the concentrations ofthe reactants. For the general reaction between AA and BB,
aA+bB⇌cC+dDaA+bB⇌cC+dD
The dependence of the reaction rate on the concentration of eachreactant is given by the equation called the rate law:
rate=k[A]m[B]nrate=k[A]m[B]n
where kkk  is a proportionality constant called therate constant. The exponent mmm  determines the reactionorder with respect to AA, and nnn determines the reaction orderwith respect to BB. The overall reaction order equals the sum ofthe exponents (m+nm+n).
Part A: What is the reaction order with respectto A? **Express your answer as an integer.
Part B: What is the reaction order with respectto B? **Express your answer as an integer.
Part C: What is the reaction order with respectto C? **Express your answer as an integer.
