Select the correct collision theory explanation for changing the rate of the given chemical reaction.

Chemistry

GarryVolchara [31]3 years ago

Explanation:

According to collision theory, more is the number of collisions between solute and solvent particles more will be the rate of reaction.

  • Refrigerate food to keep it from spoiling - Here particles will collide with less force as decrease in temperature will cause an increase in potential energy of particles.
  • Add inert water to a reaction solution - Here also particles will collide less frequently.
  • Compress the air/fuel mixture inside an engine cylinder with a piston - Here particles will collide more frequently as increasing the pressure will bring the molecules close to each other and thus there will be more number of collisions.
  • Raise the boiling point of water with a pressure cooker - Increase in temperature will also cause increase in number of collisions.
  • Grind a metal into a fine powder - More surface area will also provide more number of collisions.

Yuki888 [10]

Answer:

C. Water passes into the salt solution, dehydrating bacterial cells and making them harmless.

Explanation:

The salt solution is hypertonic to the bacterial cells and as such, water molecules will move from the bacterial cells into the salt solution, dehydrating the cells and rendering them harmless.

Option A is also true but it is irrelevant to the question asked. Option B and D are wrong.

The correct option is C.

zhuklara [117]

Answer:

Option D is correct.

Explanation:

Compared to a sample of helium at STP, the same sample of helium at a higher temperature and a lower pressure because any gas at a higher temperature and a lower pressure will  behaves like  an ideal gas. for eg.

nitrogen at STP show its behavior as an ideal gas.

When pressure of a gas increased & temperature is decreased then the gas does not follow ideal gas law.

Therefore option D is correct.

A 5.00 mL sample of hydrochloric acid is titrated with 0.1293 M ammonia (a base). If the titration required 28.15 mL of ammonia,
Sladkaya [172]

Answer:

1. C = 0.73 M.

2. pH = 0.14

       

Explanation:

The reaction is the following:

HCl + NH₃ ⇄ NH₄⁺Cl⁻

From the titration, we can find the number of moles of HCl that were neutralized by the ammonia.

n_{a} = n_{b}

Where "a" is for acid and "b" is for base.

The number of moles is:

n = C*V  

Where "C" is for concentration and "V" for volume.

C_{a}V_{a} = C_{b}V_{b}

C_{a} = \frac{0.1293 M*28.15 mL}{5.00 mL} = 0.73 M

Hence the initial concentration of the acid is 0.73 M.

The original pH of the acid is given by:

pH = -log([H^{+}])

pH = -log(0.73) = 0.14          

Therefore, the original pH of the acid is 0.14.

I hope it helps you!
