The molar heat capacity cp, m of so2(g) is described by the following equation over the range 300 k < t < 1700 k: cp, mr=3.093+6.967×10−3tk−45.81×10−7t2k 2+1.035×10−9t3k3 in this equation, t is the absolute temperature in kelvin. the ratios tn/kn ensure that cp, m has the correct dimension. 1.85 moles of so2(g) is heated from 34.0 ∘c to 1190 ∘c at a constant pressure of 1 bar. explain the sign of w.

In vapor-liquid equilibrium in a binary mixture, both components are generally present in both phases. how many degrees of freedom are there for such a system? the reaction between nitrogen and hydrogen to form ammonia occurs in the gas phase. how many degrees of freedom are there for this system? steam and coal react at high temperatures to form hydrogen, carbon monoxide, carbon dioxide, and methane. the following reactions have been suggested as being involved in the chemical transformation:
