Mechanism of hypothetical reaction `X_(2) + Y_(2) to 2 XY` is given below (i) `X_(2) to X + X ` (fast ) (ii) `X + Y_(2) hArr XY + Y` (slow) (iii) ` X + Y to XY` (fast) The overall order of the reaction will beA. 2B. 0C. 1.5D. 1 |

Answer» Correct Answer - c According to law of mass action r = `K [X] [Y_(2)] " " … (i)` From fast step `K_(eq) = ([X]^(2))/([X_(2)])` `[X]^(2) = K_(eq) [X_(2)]` [X] = `sqrt(K_(eq))[X_(2)]^(1//2) …. (ii)` From equation (i) & (ii) `r = K [X_(2)]^(1//2) [Y_(2)]` `r = K[X_(2)]^(1//2) [Y_(2)]` . Overall order of reaction = 1 + 0.5 = 1.5 |
