1.	The rate of a gaseous reaction triples when temperature is increased by 10^(@)C from 25^(@)C. The energy of activation of the reaction in kJ mol^(-1) will be
Answer» 410 735 514 205 Solution :`"log"(3K)/(k)=(E_(a))/(2.303xx8.314 "JK mol"^(-1))XX(298K-283K)/(298Kxx283K)` `:. log 3=(E_(a))/(19.15)xx(15)/(298 xx 283)` `0.4771 =(E_(a)xx15)/(19.15xx298xx283)` or `E_(a)=(0.4771xx19.15xx298xx283)/(15)` `=513.68"kJ mol"^(-1)`.
