The ideal gas equation allows prtkc .izu-y9;xw,29o8 txace j9 gs;jm essure to be calcuzbay .6j9clq.lated according to the equation,
.lbq 9a. 6zjyc P=$\frac{nRT}{V}$.
This allows a straight line to be drawn for the effect of $\frac{1}{V}$ on P.
For the sketched graph above, which components of the equation P=$\frac{nRT}{V}$,relate to the gradient and
y-intercept of the straight line?
A. Gradient is nRT;y-intercept is V
B. Gradient is nRT;y-intercept is 0
C. Gradient is $\frac{1}{V}$;y-intercept is P
D. Gradient is$\frac{nRT}{V}$;y-intercept is P
