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
