(Solved): The Rate Constant Of The Elementary Reaction 2HI(g) H2(g) +I2(g) Is K = 2.47 L Mol-1 S-1 At 611°C, ...


The rate constant of the elementary reaction 2HI(g) H2(g) +I2(g) is k = 2.47 L mol-1 s-1 at 611°C, and the reaction has an activation energy of 206 kJ mol-1.

(a) Compute the rate constant of the reaction at a temperature of 772°C.

(answer in L mol-1 s-1 )

(b) At a temperature of 611°C, 143 s is required for half of the HI originally present to be consumed. How long will it take to consume half of the reactant if an identical experiment is performed at 772°C? (answer in seconds)
