Question

The optimum temperature progression for exothermic reversible reaction is ____

(a) The locus of maximum rates

(b) Highest allowable temperature

(c) The isothermal path

(d) Lowest allowable temperature

Answer 1

Right answer is (a) The locus of maximum rates

For explanation: For a reversible exothermic reaction, the rate of forward reaction increases but the maximum attainable conversion decreases. Hence, it starts at high temperature which decreases as conversion rises.
