B) The △G is negative and the reaction is non-spontaneous.
C) The △G is positive and the reaction is spontaneous.
Can adding a catalyst make a non-spontaneous reaction spontaneous? If yes, how (what does the catalyst do that makes the reaction spontaneous?), and if no, why not?
Label the following statements true or false:
