In an equilibrium reaction gases Q2 and R2 form QR the energy content of the reactant is 100kj and that of the products 54kj . the energy content of the activated complex is 210kj Draw the energy profile diagram of the reactant and determine the activation energy of the reaction and write a balanced equation for the reaction and state whether it's exothermic or endothermic

4r-134a enters the condenser of a residential heat pump at 800 kpa and 50°c at a rate of 0.022 kg/s and leaves at 750 kpa subcooled by 3°c. the refrigerant enters the compressor at 200 kpa superheated by 4°c determine (a) the isentropic efficiency of the compressor, (b) the rate of heat supplied to the heated room, and (c) the cop of the heat pump. also, determine (d) the cop and rate of heat supplied to the heated room if this heat pump operated on the ideal vapor-compression cycle between the pressure limits of 200 and 800 kpa.
