Assuming constant pressure, rank these reactions from most energy released by the system to most energy absorbed by the system, based on the following descriptions: A. Surroundings get colder and the system decreases in volume. B. Surroundings get hotter and the system expands in volume. C. Surroundings get hotter and the system decreases in volume. D. Surroundings get hotter and the system does not change in volume. Also assume that the magnitude of the energy changes due to volume and temperature changes are similar among the reactions. Rank from most energy released to most energy absorbed by the system. To rank items as equivalent, overlap them. ► View Available Hint(s) Most energy released Submit Reaction B Reaction D Reaction C Part B Reset Help Reaction A Most energy absorbed At a constant external pressure of 43.6 bar, a mole of X reacts via the reaction X(g) +4Y(g)→2Z(g), AH-75.0 kJ mol-¹ Before the reaction, the volume of the gaseous mixture was 5.00 L.
