An initial mixture of nitrogen gas and hydrogen gas is reacted in a rigid container at a certain temperature by the reaction

3H2(g) +N2(g) <=> 2NH3(g)
At equilibrium the concentrations are [H2]=5.0 M, [N2]= 8.0M, [NH3]=3.0M
What were the concentrations of nitrogen gas and hydrogen gas that were reacted initially.

35. a insulated cylinder of solid gold (k 310 kw/m-k) of radius v2 m and height 5 m is heated at one end until the temperature at each point in the cylinder is given by w(r, y, z) (30 z2)(2-(r2+ y2). determine the rate of heat flow across each horizontal disk given by z 1, z 2, and z 3, identifying which has the greatest rate of heat flow across it.
