Answer 1

Hello !!

Combustion reactions, such as this fire, are spontaneous reactions. It is a highly endothermic reaction with a slightly positive entropy change

Thanks!!

Answer 2

This combination of a decrease in energy and an increase in entropy means that combustion reactions occur spontaneously. Combustion reactions, such as this fire, are spontaneous reactions. ... It is a highly endothermic reaction with a slightly positive entropy change (ΔS).

Hope you understand
