The work done during an isothermal expansion is given by W = nRT ln(V2/V1).

For an ideal gas undergoing isothermal expansion, the work done is given by W = nRT ln(Vf/Vi).

Work done (W) = P * ΔV = 2 atm * (2 L - 4 L) = 2 atm * (-2 L) = -4 L·atm (work done on the gas is positive).

Setting y = 0 in the equation gives 5x = 10, thus x = 2. The x-intercept is 2.

Setting y = 0 in the equation gives 5x + 10 = 0, thus x = -2.

Setting y = 0 in the equation gives 6x = 12, thus x = 2. The x-intercept is 2.

Rearranging gives y = (2/3)x + 2; y-intercept = 2

To find y-intercept, set x = 0: 2(0) - 3y = 6 => -3y = 6 => y = -2

Setting x = 0, we get -2y = 6, so y = -3.

Set x = 0: -2y = 6 => y = -3, y-intercept is 3.

Setting x = 0, we get -4y = 12, so y = -3.

Setting x = 0 in the equation gives 5y = 20, thus y = 4. The y-intercept is 4.

Chemisorption is characterized by the formation of a chemical bond between the adsorbate and the surface.
