The reaction C8H18(l) + 90O2(g) → 7CO2(g) + 4H2O(l) is exothermic in nature. The reaction would be

Understand the Problem

The question is asking about the spontaneity of an exothermic reaction involving C8H18 and O2, and how it behaves at different temperatures. It presents multiple options regarding spontaneous behavior.

More Information

Exothermic reactions release energy, making them generally more likely to be spontaneous at lower temperatures.

Tips

Remember that while enthalpy favors spontaneity at low temperatures for exothermic reactions, entropy plays a crucial role at high temperatures.
