Question
Chapter 1, Problem 22CQ
Summary Introduction
To determine: Whether enthalpy increases or decreases during the reaction when equilibrium constant, Keq is 100 at 10°C and Keq is 10 at 30°C.
Introduction: Enthalpy is the internal energy in a system. Exothermic and endothermic reactions cause differences in enthalpy.
