Given that the reduced temperature, = T T_C the reduced pressure, = F F_C the reduced volume, = V V_C Thus, it can be said that the reduced equation of state may be given as
Options
- A( 3 + 1 )(3 -1)= 8 3
- B( 4 + 1 )(3 -1)= 3 8
- C( 3 + 1 )( -1)= 3 8
- D( 3 + 1 ^2 )(3 -1)= 8 3
Correct answer
D. ( 3 + 1 ^2 )(3 -1)= 8 3
Step-by-step solution
aligned p & =p_C = ( a 27 b^2 ) V & =V_C =(3 b) T & =T_C = ( 8 a 27 R b ) aligned Thus, substituting in the van der Waals' equation, (p+ a V₂ )(V-b)=R T or ( + 3 ^2 )(3 -1)=8 This is reduced state equation or, ( 3 + 1 ^2 )(3 -1)= 8 3
