In the first order thermal decomposition of C_2H_5I(g) to C_2H_4 (g) + HI(g), the reactant in the beginning exerts a pressure of 2 bar in a closed vessel at 600 K. IF the partial pressure of the reactant is 0.1 bar after 100 minutes at the same temperature the rate constant in min^-1 is (log 2=0.3010) |

Answer» `6.0 TIMES 10^-4` at t=0 2BAR 0 0 After 1000 MINUTES `0.1 (2-0.1) (2-0.1) =1.9 =1.9 Since, the reaction in first order. `k=2.303/t log""p/(p_0-x)` `k=2.303/1000 log""2/(2-1.9)` `=2.303/1000log 20` `k=3 times 10^-3 min^-1` |
