For the following questions, use the reaction NO2(g) - 1/2 N2(g) + O2(g), with ΔH = –33.1 kJ/mol and ΔS = 0.06302 kJ/(mol·K) i. Draw a possible potential energy diagram of the reaction. Label the enthalpy of the reaction

ii. Is the reaction endothermic or exothermic? Explain your answer

iii. What is the Gibbs free energy of the reaction at 298 K

iv. Is the reaction spontaneous or nonspontaneous at 298 K? Explain your answer

please no fake answers I worked hard to get these points :/

Which is a difference between molecular compounds and ionic compounds? select the correct answer below: question 5 options: molecular compounds typically form between a metal and a nonmetal, while ionic compounds typically form between nonmetals. molecular compounds result from the transfer of electrons between atoms to form ions, while ionic compounds result from the sharing of electrons between neutral atoms. molecular compounds are formed of discrete, neutral molecules, while ionic compounds are formed of large repeating arrays of opposite charges. molecular compounds have high melting points and high boiling points, while ionic
