The following data are obtained for a reaction, `X+Yrarr"Products"`. `{:("Expt. ",[X_(0)]//"mol ",[Y_(0)]//"mol ","rate/mol L"^(-1)s^(-1)),(1,0.25,0.25,1.0xx10^(-6)),(2,0.50,0.25,4.0xx10^(-6)),(3,0.25,0.50,8.0xx10^(-6)):}` The overall of the reaction isA. 2B. 4C. 3D. 5 |

Answer» Correct Answer - D `r=K[X]^(x)[Y]^(y)` Total order n = x + y By exp. (1) & (2) `(r_(1))/(r_(2))=(K[.25]^(x)[.25]^(y))/(K[.50]^(x)[.25]^(y))=(1.0xx10^(-6))/(4.0xx10^(-6))` `(1)/((2)^(x))=(1)/(4),x=2` By exp. (1) & (3) `(r_(1))/(r_(2))=(K[.25]^(x)[.25]^(y))/(K[.25]^(x)[.50]^(y))=(1xx10^(-6))/(8xx10^(-6))` `(1)/((2)^(4))=(1)/(8),y=3` So Total order `=2+3=5` |
