Ethane (component A - C2H6) and hydrogen (component B) are fed to a differential reactor where they react on the catalyst to form methane (component C - CH4) at 300K. The amount of catalyst is 10 grams. The reaction is irreversible. The total molar feed rate into the reactor is 1.70 mol/h. Total pressure is one atm. The mole fraction of ethane at the inlet is 0.5. There are no inerts in the feed.

Required:
a. Write the stoichiometric equation for this reaction.
b. Find the concentrations of ethane and hydrogen at the inlet.

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.
