At a certain temperature this reaction follows second-order kinetics with a rate constant of $3.37 \times 10^{-4} \text{M}^{-1} \text{s}^{-1}$: $2NH_3(g) \longrightarrow N_2(g) + 3H_2(g)$ Suppose a vessel contains $NH_3$ at a concentration of 0.660 M. Calculate the concentration of $NH_3$ in the vessel 1.80 seconds later. You may assume no other reaction is important. Round your answer to 2 significant digits.

Problem 5. An iron pipe carrying hot air at 50 $^\circ$C is surrounded by cool air at 0 $^\circ$C. How much can the heat loss from the pipe be reduced if the outside surface of the pipe is covered with a layer of insulation? Give your answer in % reduction. Neglect heat radiation and contact resistance between the pipe and the insulation. Include sketches of the given system and of the equivalent thermal circuit(s). Material properties: $k_{iron} = 80 \frac{W}{m\cdot K}$ $k_{insulation} = 0.1 \frac{W}{m\cdot K}$ 1000 mm = 100 cm = 1 m hot air: $h_i = 20 \frac{W}{m^2 \cdot K}$ cool air: $h_o = 80 \frac{W}{m^2 \cdot K}$ Iron pipe: inside diameter = 4 cm; pipe wall thickness = 6 mm; insulation thickness = 10 mm
