The initial rates of reaction 3A + 2B + C to Products, at different i

1.	The initial rates of reaction 3A + 2B + C to Products, at different initial concentrations are given below The order with the respect to the reactants A, B and C are respectively.
Answer» 3,2,0 3,2,1 2,2,0 2,2,1 Solution :E) The rate law equation may be expressed as: Rate =`k[A]^(p)[B]^(Q)[C]^( r)` By compairing the data from 1st and 2nd sets, the concentration of 'A' and 'B' are constants. When the concentration of 'C' is made thrice, there is no change in the initial rate. `therefore` The order with respect to `c'`=0 Now, let us compare data from 3RD and 1st sets. `(1.0 xx 10^(-2))/(5.0 xx 10^(-3))= (0.010)^(q)/(0.005)^(q)` `(2)^(1) = (2)^(q)` Order with respect to B=1 Now, let us compare data from 4th and 1st sets.s `(1.25 xx 10^(-3))/(5.0 xx 10^(-3)) = (0.005)^(p)/(0.010)^(p)` `(1/4) = (1/2)^(p)` `(1/2)^(2) = (1/2)^(p)` Order with respect to A=2 Thus, the order with respect to A, B and C are: 2,1,0. Thus, the order with respect to A, B and C are: 2,1,0.
