The rate constant of the elementary reaction
C$_2$H$_5$Cl(g) → C$_2$H$_4$(g) + HCl(g)
is $k = 7.28 \times 10^{-5} s^{-1}$ at 428 °C, and the reaction has an activation energy of 237 kJ/mol.
Compute the rate constant of the reaction at a temperature of 465 °C.
$k = \boxed{}$ s$^{-1}$
At a temperature of 428 °C, 9.52 x 10$^3$ s is required for half of the C$_2$H$_5$Cl originally present to be consumed. How long will it take to consume half of the reactant if an identical experiment is performed at 465 °C?
$t = \boxed{}$ s
