The rate constant of the elementary reaction C4H5(g)+2C2H4(g) is k=1.15104s1 at 426C, and the reaction has an activation energy of 261kJ/mol. Compute the rate constant of the reaction at a temperature of 461C. k= At a temperature of 426C,6.03103is required for half of the C4H5 orlginally present to be consumed. How long will it take to consume half of the reactant if an identical experiment is performed at 461C ? t=
