A reaction will occur spontaneously if a There is an increas

A reaction will occur spontaneously if a. There is an increase in entropy b. There is an increase in free energy c. There is a decrease in free energy d. Heat is absorbed A decrease in entropy in a reaction (A + Delta S_system) can be overcome by a. An increase in entropy in the surroundings (-delta S_surrounding) b. If the temperature of the reaction is lower than the ratio of Delta H/I Delta S c. If the temperature of the reaction is greater than the ratio of Delta H/Delta S d. Both a and b are correct

Solution

16

(a) there is an increase in entropy

A reaction will happen spontaneously, without added energy, if it increases the entropy as a whole.
