The reaction CH₃CH₂CH₂CH₃(g)$\rightarrow$CH₃CH(CH₃)₂(g),is exothermic.This reaction will be spontaneous at high temperatures.

Question

Quizplus · Accepted Answer

An exothermic reaction releases heat, decreasing the system's enthalpy ($\Delta H < 0$). According to Gibbs free energy equation ($\Delta G = \Delta H - T\Delta S$), if $\Delta S$ (entropy change) is negative or small positive, increasing temperature ($T$) makes $\Delta G$ more likely to be positive, making the reaction non-spontaneous at high temperatures.

The Reaction CH3CH2CH2CH3(g) →\rightarrow→ CH3CH(CH3)2(g),is Exothermic

The Reaction CH₃CH₂CH₂CH₃(g) $\rightarrow$ CH₃CH(CH₃)₂(g),is Exothermic
