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 \[\Delta H=-2.5\times {{10}^{3}}cal\] \[\Delta S=7.4\,\,cal\,\,{{\deg }^{-1}}\] \[T=298\,K\] \[\Delta G=\Delta H-T\Delta S\] \[=(-2.5\times {{10}^{3}})-(298\times 7.4)\] \[=-2500-2205\] = 4705 cal The reaction is spontaneous because \[\Delta G\] is negative.You need to login to perform this action.
