Isopropanol (C3H8O) reacts with sulfuric acid at 50 °C according to the equation below. A plot ofln[C3H8O] vs. time is linear with a slope of –1.3 x 10–5. At 125 °C the rate constant is 8.0 x 10–3mol–1L s–1. C3H8O + H2SO4→C3H6+ H2O
a)Calculate the energy of activation (in kJ) for the forward process.
b)Calculate the frequency factor, A.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
