Question
Constants Beriodis Table Part A Energy cannot be created nor destroyed, but it can be ransferred between a reaction and its surroundings The change in energy, E, is positive if the reaction absorbs energy, and it is negative if the reaction releases energy You may also see this expressed in terms of change in intermal energy AU For the purposes of this 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 Surmoundings get colder and the system decreases in volume. B Surroundings get hoter and the system expands in volume queston, U and E are equal. Surroundings get hotter and the system decreases in volume D Surmoundings get hotter and the system does not change in volume. One way a reaction can transfer energy to or from the surroundings is by releasing or absorbing Heat A reaction can also transfer energy ins the form of work, through a change in vokume. The total change in energy is the sum of the heat and work Also assume that the magnitude of the volume and bemperature changes are similar among the reactions Rank from most energy released to most energy absorbed. To rank items as equivalent, overlap them View Available Hint Rese Help At constant pressure, q 11 and w--PAV and soExplanation / Answer
The correct order will be Reaction C, Reaction D, Reaction B, Reaction A
Explaination:
Since in the Reaction C, the surrounding get hotter it means more energy is being released by the system and also work is done by the system because the volume is decreasing. So both factors are working here. So Reaction C will be on first number.
In Reaction D, the surroundings get hotter it means energy is being released and no work is done because no change in volume. Here only one factor is effective that is released energy. Soit comes on second no..
In Reaction B, the surroundings get hotter it means energy is being released and work is done on the system because volume of the system is increasing. it means some heat is lost in order to perform work on the system. So Reaction B is in third position.
In Reaction A, the surroundings get colder it means energy is being absorbed from the surroundings. So it will come at the last position in rank according to the question.
