JEE MAIN - Chemistry (2019 - 11th January Evening Slot - No. 15)
The standard reaction Gibbs energy for a chemical reaction at an absolute temperature T is given by
$$\Delta $$rGo = A – BT
Where A and B are non-zero constants. Which of the following is TRUE about this reaction?
Where A and B are non-zero constants. Which of the following is TRUE about this reaction?
Exothermic if B < 0
Endothermic if A > 0
Exothermic if A > 0 and B < 0
Endothermic if A < 0 and B > 0
Explanation
$$\Delta $$Go = $$\Delta $$Ho - T$$\Delta $$So
Given that A and B are non-zero constants, i.e., A = $$\Delta $$Ho, B = $$\Delta $$So
If $$\Delta $$Ho is positive means reaction is endothermic.
Given that A and B are non-zero constants, i.e., A = $$\Delta $$Ho, B = $$\Delta $$So
If $$\Delta $$Ho is positive means reaction is endothermic.
