QJEEM19Ch510b: JEE Main 2019 Chemistry - Class 11 JEEM19Ch510b Solution: The standard reaction Gibbs energy for a chemical reaction at…

The standard reaction Gibbs energy for a chemical reaction at an absolute temperature T is given by ΔrGo = A – BT

Where A and B are non-zero constants. Which of the following is TRUE about this reaction?

Multiple Choice Options

  • A Exothermic if B < 0
  • B Endothermic if A > 0
  • C Exothermic if A > 0 and B < 0
  • D Endothermic if A < 0 and B > 0

Step-by-Step Verified Solution

ΔGo = ΔHo - TΔSo

Given that A and B are non-zero constants, i.e., A = ΔHo, B = ΔSo

If ΔHo is positive means reaction is endothermic.
