How does the value of ∆ r S° affect the equilibrium constant (K) for a chemical reaction?
Options
- A∆ r S° has no effect on K
- B∆ r S° always increases K
- C∆,rS° always decreases K
- DThe effect of ∆ r S° on K depends on whether ∆ r S° is positive or negative
Correct answer
D. The effect of ∆ r S° on K depends on whether ∆ r S° is positive or negative
Step-by-step solution
The effect of ∆ r S° on the equilibrium constant (K) depends on whether ∆ r S° is positive or negative. If ∆ r S° is positive, it tends to increase K, and if ∆ r S° is negative, it tends to decrease K.
