For the reaction a+b↽−−⇀c+da+b↽−−⇀c+d , assume that the standard change in free energy has a positive value. changing the conditions of the reaction can alter the value of the change in free energy (δδg) . classify the conditions as to whether each would decrease the value of δδg , increase the value of δδg , or not change the value of δδg for the reaction. for each change, assume that the other variables are kept constan

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
