Question

Consider the following statements:
The coefficient B in the virile equation on state PV${}_m$ = RT( 1 + $\frac{B}{V_m}$ + $\frac{B}{V_m}$ +...)
a. is independent of temperature
b.is equal to zero at boyle temperature
c. has the dimension of molar volume
Which of the above statements are correct :

• A. a and b
• B. a and c
• C. b and c
• D. a, b and c

Answer 1

The correct option is C b and c

The statements b and c are true.
The coefficient B in the virile equation on state $P{V}_m=RT(1+\frac{B}{V_m}$ + $\frac{B}{V_m}$ +...)

b.is equal to zero at boyle temperature. At this temperature, the real gas behaves like ideal gas and the viral equation becomes ideal gas equation $P{V}_m=RT$

c. has the dimension of molar volume. This is because in the viral equation, it appears in the form of the ratio $B/V_m$
