Which of the following graph correctly represents the plots of $ ext{K}_ ext{H}$ at 1 bar gases in water versus temperature ? [Diagram: Four graphs showing Henry's constant (KH) on y-axis and temperature (t/°C) on x-axis for different gases (O2, N2, He, CH4). (1) KH for O2, N2, He decreases with temperature. (2) KH for O2, N2, He increases with temperature. (3) KH for He, N2, O2 shows a minimum. (4) KH for He, N2, CH4 shows a minimum, but order is He N2 CH4.]

Which of the following graph correctly represents the plots of $	ext{K}_	ext{H}$ at 1 bar gases in water versus temperature ? [Diagram: Four graphs showing Henry's constant (KH) on y-axis and temperature (t/°C) on x-axis for different gases (O2, N2, He, CH4). (1) KH for O2, N2, He decreases with temperature. (2) KH for O2, N2, He increases with temperature. (3) KH for He, N2, O2 shows a minimum. (4) KH for He, N2, CH4 shows a minimum, but order is He > N2 > CH4.]
