Minnie Mouse, a well-known investor in the Orlando area, has been returning substantial profits for her clients over the last ten years. With a recent declinein th estock market and trading, the returns have ceased to exist and phone calls are not being returned to clients looking to remove their investments before the market crashes. Ms. Mouse is believed to be involved in a _____________, or an investment fraud that involves the payment of purported returns to existing investors from funds contributed by new investors.

In a catalytic converter, nitrogen dioxide, NO2, undergoes metal catalyzed reduction to form nitrogen, N2, and oxygen, O2. The balanced equation is provided below. The equation is written with an unconventional coefficient of 1/2 for nitrogen so that the equation is for 1 mole of nitrogen dioxide, so that energies can easily be calculated per mole. NO2(g)   →  1/2 N2(g)  +  O2(g) ΔHr = -33 kJ/mol ΔSr = +61 J/mol.K Given the provided enthalpy and entropy of reaction values, determine the Gibbs energy of this reaction at 25°C, which is close to normal temperature (not the usual temperature of a catalytic converter), and decide if the reaction is spontaneous or not at this temperature, 25°C. Use the equation ΔG = ΔH – TΔS and remember to use the correct units throughout. K = °C + 273. Calculate ΔG to 1 decimal place
