For the solution of the gases w , x , y and z in water at 298 K , the Henry's law constants ( K H ) are 0.5, 2 , 35 and 40 k b a r , respectively. The correct plot for the given data is:

Step-by-step solution

P g a s = K H . X g a s Where, P g a s is the partial pressure of gas. K H is the Henry’s constant X g a s is the mole fraction of gas P g a s = K H 1 - X H 2 O P g a s = K H - K H X H 2 O On comparing this with the equation of straight line, y = mx + c , the intercept, c = K H . Thus, the gas having more value of Henry's law constant will have more value of intercept on the y-axis.
