Spontaneous Processes
Which of the following processes are spontaneous?
(a) building a sand castle
(b) outlining your chemistry notes
(c) wind scattering leaves in a pile
(a)
Interpretation:
Whether building a sand castle is spontaneous process or not should be determined.
Concept introduction:
The process which has natural tendency to take place, no external input is required is known as spontaneous process. It is also defined as the process which takes place own its own.
The process in which external input is required continuously is known as non-spontaneous process.
Answer to Problem 1QAP
Non-spontaneous
Explanation of Solution
The given process is building a sand castle.
In order to build a sand castle, continuous external source or intervention from outside is needed that is in the form of man power. Thus, the process is non-spontaneous.
(b)
Interpretation:
Whether outlining your chemistry notes is spontaneous process or not should be determined.
Concept introduction:
The process which has natural tendency to take place, no external input is required is known as spontaneous process. It is also defined as the process which takes place own its own.
The process in which external input is required continuously is known as non-spontaneous process.
Answer to Problem 1QAP
Non-spontaneous
Explanation of Solution
The given process is outlining your chemistry notes.
In order to outline the chemistry notes, external input is needed as notes can’t be outlined on its own. Thus, the process is non-spontaneous.
(c)
Interpretation:
Whether wind scattering leaves in pile is spontaneous process or not should be determined.
Concept introduction:
The process which has natural tendency to take place, no external input is required is known as spontaneous process. It is also defined as the process which takes place own its own.
The process in which external input is required continuously is known as non-spontaneous process.
Answer to Problem 1QAP
Spontaneous
Explanation of Solution
The given process is wind scattering leaves in pile.
Wind has ability to scatter the pile of leaves in every direction without any intervention from outside. Thus, the process is spontaneous.

- Consider the decomposition of red mercury(II) oxide under standard state conditions.. 2HgO(s,red)2Hg(l)+O2(g) (a) Is the decomposition spontaneous under standard state conditions? (b) Above what temperature does the reaction become spontaneous?arrow_forwardWhat is a spontaneous reaction?arrow_forward9.72 Although it can be a nuisance when a laptop computer freezes up and needs to be rebooted, we accept that as somewhat inevitable. But clearly the need to occasionally reboot the control system for the power grid would not be acceptable. Use the web to research ways that engineers ensure the reliability of crucial systems like the control infrastructure of the grid, and write a paragraph summarizing the main strategies employed.arrow_forward
