Rank the following reactions in terms of increasing ?E for the reaction system (from most negative to most positive). All occur at a constant pressure of 1.000 atm.
Reaction 1: The surroundings get 25°C colder and the system expands from 1.0L to 5.0L.
Reaction 2: The surroundings get 25°C colder and the system contracts from 5.0L to 1.0L.
Reaction 3: The surroundings get 25°C warmer and the system expands from 1.0L to 5.0L.
a)Reaction 2 < Reaction 3 < Reaction 1
b)Reaction 3 < Reaction 1 < Reaction 2
