NEET Chemistry (general) MCQ Question
Type: MCQ-numerical-Easy-Class 11
Calculate the equilibrium constant (K) for a reaction with ∆rH = -286 kJ mol⁻¹ and ∆rS = 100 J K⁻¹ mol⁻¹ at 300 K.
A
Greater than 1
B
Less than 1
C
Equal to 1
D
Cannot determine
Correct Answer
Option A
Detailed Explanation
According to chunk 3, for exothermic reactions (negative ∆rH ) with positive ∆rS , ∆rG is likely to be negative, leading to a large K, greater than 1.
