A cylinder is initially filled with saturated vapor mixture of R-134a at a specified pressure. Heat is transferred to the cylinder until the refrigerant vaporizes complately at constant pressure. The initial volume, the work done and the total heat transfer are to be determined (x1 = 0,25 m = 0,2 kg, p = 200 kPa)

Fill in the coefficients that will balance the following reaction: a0cr2(so4)3 + a1agno3 -> a2cr(no3)3 + a3ag2so4
