The equation of state for a redlich-Kwong gas is p(t)= [(rt/v-b)-(a/v(v-b)t^-1/2)] where r, a,and b are constants. Fix the volume...

The equation of state for a redlich-Kwong gas is p(t)= [(rt/v-b)-(a/v(v-b)t^-1/2)] where r, a,and b are constants. Fix the volume and calculate the internal pressure of bettholot gas.
