2.1.State a correctly balanced equation that represents the complete combustion of butane.
2.2.Using section 12 (Section 13- 2025 Syllabus) of the data booklet, calculate the Gibbs free energy change of this reaction.
ΔG$_{reaction}$=- kJ mol$^{-1}$
2.3.State, with a reason, whether this reaction is spontaneous or not.
Important note: The section numbers mentioned in the video solution are specific to the 2024 syllabus.
You can refer to the question stem to find the section numbers in the 2025 syllabus.
