34、 In Figure 34, two tanks are connected by a valve. One tank contains 2 kg of carbon monoxideat 77°C and 0.7 bar. The other tank holds 8 kg of the same gas at 27°C and 1.2 bar. The valve isopened and the gases are allowed to mix while receiving energy by heat transfer fromsurroundings. The final equilibrium temperature is 42°C. Using the ideal gas modelp mRT V = /and the constant volume specific heat Cv=0.745 kJ/kgK, which of the followingstatements is correct? 

(A) The final equilibrium pressure is 5.0 bar,
(B) the final equilibrium pressure is 1.05 bar,
(C) the heat transfer rate is 37.25 kJ,
(D) the heat transfer rate is 47.25 kJ.
