Question 1 Consider the Relich-Kwong equation of state P = \frac{RT}{v-b} - \frac{a}{v(v+b)\sqrt{T}}P=v−bRT−v(v +b)Ta

For methane, a = 32.19a=32.19 bar(m^33/(kg\cdot⋅mol) )^22 K^{0.5}0.5 and b = 0.02969b=0.02969 m^33/(kg\cdot⋅mol) .

Find the specific volume at the critical point predicted by this equation in m^33/kmol.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
