For the reaction given below, the standard change in free energy has a positive value. A+B<-->C+D Changing the conditions of the reaction can alter the value of the change in free energy (?G). Sort the following conditions as to whether each would decrease the free energy value, increase the free energy value, or not change the free energy value for the reaction. For each change, assume that the other variables are kept constant. a. Adding a catalyst decrease the free...

For the reaction A+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 (AG). Classify the conditions as to whether each would decrease the value of AG, increase the value of AG, or not change the value of AG for the reaction. For each change, assume that the other variables are kept constant. Decrease AG Increase AG No effect on...
