What is the mole fraction of acetic acid in a solution containing 2 moles of vinegar and 3 moles of water? A. 2 B. 3 C. 0.4 D. 0
9966 [12]

Answer:

C. 0.4.

Explanation:

<em>∵ mole fraction of acetic acid (X acetic acid) = (no. of moles acetic acid)/(total no. of moles) = (no. of moles acetic acid)/(no. of moles of acetic acid + no. of moles of water).</em>

<em></em>

- no. of moles of acetic acid = 2, no. of moles of water = 3.

- Total no. of moles = no. of moles of acetic acid + no. of moles of water = 2 + 3 = 5.

<em>∴ mole fraction of acetic acid (X acetic acid) = (no. of moles acetic acid)/(total no. of moles) =</em> (2)/(5)<em> = 0.4.</em>

Someone please help me ASAP!​
stealth61 [152]

Answer:

Increasing the temperature of the reactants

Explanation:

This causes more vibrations to occur, hence increasing the kinetic energy of the particles. The number of particles with activation energy would increase as well because they have higher kinetic energy. Kinetic energy is also the reason why the collision between particles increases. And the frequency of effective collisions increases because of the kinetic energy as well, keep in mind the particles must also be orientated in the correct way as well.
