Question #224800

8. An ideal gas absorbs 1.00 x 103 J of heat and simultaneously expands against a constant external pressure of 1.10 atm from an initial volume of 10.0 L to a final volume of 35.0 L. Determine the expansion work (w) and change in internal energy (ΔU) for this process.

w = ΔU =

9. For the reaction (at 25 °C): N2(g) + O2(g) ⇌ 2NO(g) Kc = 4x10-31

Calculate the value of Kp (at 25 °C) for: NO(g) ⇌ ½ N2(g) + ½ O2(g)

10. If a steady current of 15.0 A is passed through an aqueous solution of CuSO4, how long will it take to deposit 0.100 mol of Cu at the cathode?
