Question

Cuprous oxide (Cu20) is being reduced by hydrogen in a furnace at 950.0K. a) (2) Write a chemical reaction for the reduction of one mole of Cu2O(s) to form copper and water at this temperature. b) (6) How much heat [J] is released or absorbed per mole reacted? Use Cu Cp . mble宀fl 1950K, Cu20 Hf950K, H20ーー6 1,200 cal/mol, and CPH2-27.73+3.33E-3T [J/molK] sthe process exothermic or endothermie? Wihy?

Answer 1

a)Cu₂O +H₂ = 2Cu_(s)+ H₂O _(g)

c)The procee is exothermic.Exothermic process is one in which heat is evolved during a reaction.
