One method of synthesizing ethanol is through the gas-phase hydration of ethylene as shown below. c2h4 + h2o + ch oh the equilibrium constant at 125°c is 0.251. determine the equilibrium conversion and the product composition for the reaction between ethylene and water to form ethanol at the following conditions: a) a reaction mixture at 1 bar of 1: 1: 0 ethylene, water, inerts. b) a reaction mixture at 1 bar of 1: 3: 0 ethylene, water, inerts. c) a reaction mixture at 3 bar of 1: 3: 2 ethylene, water, inerts.

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.

ok whats the question if not i cannot you i need question and need a thing to answer
