The following reaction reaches equilibrium at 650°C and atmospheric pressure: N2(g) + C2H2(g) → 2HCN(g) If the system initially is an equimolar mixture of nitrogen and acetylene, what is the composition of the system at equilibrium

Air flows over a heated plate àt a velocity of 50m/s. the local skin factor coefficient at a point on a plate is 0.004. estimate the local heat transfer coefficient at this point.the following property data for air are given: density = 0.88kg/m3 , viscosity 2.286 x 10 ^-5 kgm/s , k = 0.035w/mk ,cp = 1.001kj/kgk. use colburn reynolds analogy.
