The rate of an exothermic reaction decreases with increasing temperatureaccording to Le Chatelier's principle.b. Favourable kinetics can make a reaction that takes place even if it is ther-modynamically not feasible.c. If a reaction is thermodynamically feasible, then it must take place.d. Kinetic barriers can stop a reaction even if there is a thermodynamic drivingforce for transformation.e. The rate of a reaction is more sensitive to temperature changes if the acti-vation energy is smaller.f. The rate of a reaction depends on the free energy change for the reaction.g. The "saddle point is the highest point on a potential cnergy surface.h. For a given activation energy. temperature changes have more effect on therate constant at lower temperatures.i. A process is operating at a mean temperature: the temperature oscillatingwith a fixed frequency for a given time: the extent of reaction is more if theamplitude of temperature fluctuation is greater.j. A catalyst cannot change the driving force-of a reaction.k. The rate constant of a reaction increases a hundredfold when the tempera-ture rise is 200 C. The rate constant will increasing more than fifty times ifthe temperature rise is 100
