CDP3-CB

For each of the following reactions and rate laws at low temperatures, suggest a rate law at high temperatures. The reactions are highly exothermic and therefore reversible at high temperatures.

(a) The reaction

A B

is irreversible at low temperatures and the rate law is

-rA = kCA

(a) The reaction

A + 2B 2D

is irreversible at low temperatures and the rate law is

-rA = kCA1/2CB

(a) The catalytic reaction

A + B C + D

is irreversible at low temperatures and the rate law is

In each case, make sure that the rate laws at high temperatures are thermodynamically consistant at equilibriu, (cf. Appendix C).
