Mixtures of argon and krypton are used in lasers that produce beams appearing as white light. In a batch process (e.g. not continuous) 2.5 mol Kr and 7.5 mol Ar, both initially at 1 bar and 25 C, are mixed and then compressed to produce a mixture at 248 K and 5.03 bar. Determine the work (in kJ), heat (in kJ), and change in the entropy of the universe (in J/K) involved in this process if these monatomic gasses behave ideally, the surroundings are maintained at a constant temperature of 248 K, and the efficiency of compression is 70%.
