Under given conditions, if a change is spontaneous in one direction, it is not spontaneous in the other. A. True B. False<\/p>\n\n\n\n
The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n The correct answer is A. True<\/strong>.<\/p>\n\n\n\n In thermodynamics, the spontaneity of a process is determined by the Gibbs free energy change (\u0394G). A process is considered spontaneous if the change in Gibbs free energy is negative (\u0394G < 0). If a process is spontaneous in one direction, the reverse process will have a positive Gibbs free energy change (\u0394G > 0), meaning it is non-spontaneous.<\/p>\n\n\n\n This principle is derived from the second law of thermodynamics, which states that the total entropy of the system and surroundings must increase for a process to be spontaneous. When a change occurs in one direction, it leads to an increase in the overall entropy, making the process spontaneous. However, reversing the process would decrease the entropy, making it non-spontaneous.<\/p>\n\n\n\n For example, consider the phase transition from liquid water to ice. Melting ice into liquid water is a spontaneous process at temperatures above 0\u00b0C because the entropy of the system increases as the solid structure breaks down into a liquid. However, freezing liquid water to form ice is non-spontaneous at temperatures above 0\u00b0C, because it results in a decrease in entropy. The reverse process (freezing) only becomes spontaneous at temperatures below 0\u00b0C.<\/p>\n\n\n\n In summary, spontaneity is direction-dependent. If a process is spontaneous in one direction, it will not be spontaneous in the opposite direction under the same conditions.<\/p>\n","protected":false},"excerpt":{"rendered":" Under given conditions, if a change is spontaneous in one direction, it is not spontaneous in the other.
