For the reaction: A + B = C + D AH° = -40 kJ/mol and AS° = -50 J/mol·K. The reaction under standard conditions is considered: Select one: O a. spontaneous in the reverse direction only at temperatures greater than 600 K. O b. spontaneous in the reverse direction only at temperatures greater than 800 K. O c. spontaneous in the forward direction at all temperatures. O d. spontaneous in the forward direction only at temperatures greater than 800 K.
