A gas obeys the equation of state `P(V_m – b) = RT`. The slope of the isochore will be

A

negative

B

zero

C

`R(V_(m)-b)`

D

`R/P`

Text Solution

Verified by Experts

The correct Answer is:
C
An Isochore will be a plot on the P - T graph.
`P = (RT)/(V_(m)-b)`
`therefore ((dP)/(dT))_(V_(infty)) `= slope of isochore `=R/(V_(infty)-b)`
