A) reversible
B) irreversible
C) spontaneous
D) non-spontaneous
Correct Answer: C
Solution :
Key Idea Any reaction is spontaneous when \[\Delta G\]is negative Given \[\Delta H=-2.5\times {{10}^{3}}\,\text{cal}\] \[\Delta S=7.4\,\text{cal}\,\text{de}{{\text{g}}^{-1}}\] T = 298 K \[\Delta G=\Delta H-T\Delta S\] \[=(-2.5\times {{10}^{3}})-(298\times 7.4)\] \[=-2500-2205\] \[=-4705\,\text{cal}\] The reaction is spontaneous because \[\text{G}\]is negative.You need to login to perform this action.
