Chemistry Question from JEE Main 2025 · 23 January, Shift 2

Consider a binary solution of two volatile liquid components 1 and 2. x1x_1 and y1y_1 are the mole fractions of component 1 in the liquid and vapor phase, respectively. The slope and intercept of the linear plot of 1x1\frac{1}{x_1} vs 1y1\frac{1}{y_1} are given respectively as:

  • A

    slope =p10p20= \dfrac{p_1^0}{p_2^0}, intercept =p20p10p20= \dfrac{p_2^0 - p_1^0}{p_2^0}

  • B

    slope =p20p10= \dfrac{p_2^0}{p_1^0}, intercept =p10p20p20= \dfrac{p_1^0 - p_2^0}{p_2^0}

  • C

    slope =p10p20= \dfrac{p_1^0}{p_2^0}, intercept =p10p20p20= \dfrac{p_1^0 - p_2^0}{p_2^0}

  • D

    slope =p20p10= \dfrac{p_2^0}{p_1^0}, intercept =p20p10p20= \dfrac{p_2^0 - p_1^0}{p_2^0}
