Question

The rate constant of a reaction increases by five times on increase in temperature from 27 &#176; C to 52 &#176; C . The value of activation energy in kJmol - 1 is ___ .(Rounded-off to the nearest integer) R = 8 . 314 &#160; J &#160; K - 1 &#160; mol - 1

Aicharya · Accepted Answer

T 1 = 300 &#160; K , &#160; T 2 = 325 &#160; K , &#160; K 2 = 5 &#160; K ln K 2 &#160; K 1 = Ea R 1 &#160; T 1 - 1 &#160; T 2 or, ln 5 = Ea 8 . 314 1 300 - 1 325 or, Ea = 0 . 7 &#215; 2 . 303 &#215; 8 . 314 &#215; 12 &#215; 325 = 52271 &#160; J = 52 . 271 &#160; kJ Nearest integer answer will be 52 &#160; kJ
