(Solved):
In-Class Challenge Question 1 Methane undergoes combustion with \( \mathrm{O}_{2} \) according to ...
In-Class Challenge Question 1 Methane undergoes combustion with \( \mathrm{O}_{2} \) according to the following equation: \( \mathrm{CH}_{4}(g)+2 \mathrm{O}_{2}(g) \rightarrow \mathrm{CO}_{2}(g)+2 \mathrm{H}_{2} \mathrm{O}(l)+890 \mathrm{~kJ} \) Which of the following statements are true: I. The PE of the reactants is greater than the PE of the products II. The energy diagram is drawn III. The bond energies of the reactants is greater than the bond energies of the products IV. This reaction is endothermic V. \( \Delta \mathrm{H} \) is \( (-) \) A. I, III, V B. I, II, V C. I, \( \mathrm{V} \) D. I, III, IV E. I \( -\mathrm{V} \) are true
