Given that the reaction N2(g) + 2 O2(g) → 2 NO2(g) is endothermic, what is true of the reaction 2 NO2(g) → 2 N2(g) + 2 O2(g) ?
Use the indicated average bond enthalpies to estimate the change in enthalpy, ΔHo, for the reaction between methane and iodine to produce iodomethane and hydrogen iodide:
CH4(g) + I2(g) → CH3I(g) + HI(g) ΔHo = ?
It may be helpful to draw the Lewis electron dot structure for each reactant and product; all reactants and products have single bonds.
