A student observes that the equilibrium constant for a reaction is greater than 1.0 at temperatures — Thermodynamics Chemistry Question
Question
A student observes that the equilibrium constant for a reaction is greater than 1.0 at temperatures below 500 K but less than 1.0 at temperatures above 500 K. What can the student conclude about the values of ΔH° and ΔS° for the reaction? (Assume that ΔH° and ΔS° are independent of temperature.)
A.
ΔH° > 0 and ΔS° > 0
B.
ΔH° > 0 and ΔS° < 0
C.
ΔH° < 0 and ΔS° > 0
D.✓ Correct
ΔH° < 0 and ΔS° < 0
