Consider a system of three non-interacting spins in equilibrium with a magnetic field H (this system is not really macroscopic, but is illustrative). Each spin can have only two possible orientations: parallel to H, with magnetic moment u and energy (-u H), or antiparallel with magnetic moment -u and energy (uH). a) List and identify all possible states of the system. b) If it is known that the system has an energy (-uH): i. What are the accessible states? ii....

1. Under constant-volume conditions, 4200 J of heat is added to 1.4 moles of an ideal gas. As a result, the temperature of the gas increases by 103 K. How much heat would be required to cause the same temperature change under constant-pressure conditions? Do not assume anything about whether the gas is monatomic, diatomic, etc. 2. A system gains 3080 J of heat at a constant pressure of 1.36 × 105 Pa, and its internal energy increases by 4160...

± Free Energy and Chemical Equilibrium The equilibrium constant of a system, K, can be related to the standard free energy change, ΔG, using the following equation: ΔG∘=−RTlnK where T is standard temperature in kelvins and R is equal to 8.314 J/(K⋅mol). Under conditions other than standard state, the following equation applies: ΔG=ΔG∘+RTlnQ In this equation, Q is the reaction quotient and is defined the same manner as K except that the concentrations or pressures used are not necessarily the...

� Gibbs Free Energy: Equilibrium Constant Nitric oxide, NO, also known as nitrogen monoxide, is one of the primary contributors to air pollution, acid rain, and the depletion of the ozone layer. The reaction of oxygen and nitrogen to form nitric oxide in an automobile engine is N2(g)+O2(g)?2NO(g) The spontaneity of a reaction can be determined from the free energy change for the reaction, ?G?. A reaction is spontaneous when the free energy change is less than zero. A reaction...

The equilibrium constant of a system, K, can be related to the standard free energy change, ΔG∘, using the following equation: ΔG∘=−RTlnK where T is a specified temperature in kelvins (usually 298 K) and R is equal to 8.314 J/(K⋅mol). Under conditions other than standard state, the following equation applies: ΔG=ΔG∘+RTlnQ In this equation, Q is the reaction quotient and is defined the same manner as K except that the concentrations or pressures used are not necessarily the equilibrium values....

A chain of metal links with total mass m = 6 kg is coiled up in a tight ball on a low-friction table. You pull on a link at one end of the chain with a constant force F = 69 N. Eventually the chain straightens out to its full length L = 1.1 m, and you keep pulling until you have pulled your end of the chain a total distance d = 3.9 m (diagram is not to scale)....
