For the first order reaction `2 N_(2)O_(5)(g) to 4 NO_(2) (g) + O_(2)(g)`A. The concentration of the reaction decreases exponentially with timeB. The half-life of the reaction decreases with increasing temperatureC. The half-life of the reaction depends on the initial concentration of the reactantD. The reaction proceeds to 99.6 % completion in eight half-life duration |

Answer» Correct Answer - abd `C_(t) = C_(0) e^(-kt)` `t_(1//2) prop (1)/(K) , " " K uarr` on increasing T . After eight half-lives , `C = (C_(0))/(2^(8))` `implies` % completion = `(C_(0) - (C_(0))/(2^(8)))/(C_(0)) xx 100 = 99.6%`. |
