Which condition increases the number of collisions between reactant molecules in a given volume?

Answer:

Increasing Surface Area

Explanation:

A greater surface area (meaning more, smaller particles) allows for more opportunity for particles to collide.  On the other hand, decreasing temperature and removing a catalyst would only decrease the number of collisions, and the clumping option doesn't make much sense.  Hope this helps!

Answer:

Increasing Surface Area

Explanation:

Chemical reactions occur at the atomic level where the atoms of each reacting elements interact with one another to form products. However, one way this interaction occurs is via COLLISION OF ATOMIC PARTICLES. In accordance with the collision theory, a collision must occur between reactant atomic particles in order for a reaction to take place.

However, certain factors affect the rate at which this collision occurs. One of them is the SURFACE AREA OF THE REACTANTS. Increasing the surface area of reactants simultaneously increases the frequency at which particles collide. Hence, INCREASING SURFACE AREA increases the number of collisions between reactant molecules in a given volume.

In the polypeptide Phe-Tyr-Glu-Asp-Ser-Ile-Leu-Ser what is the N-terminal amino acid?
avanturin [10]

Answer:

N-terminal Phe, C-terminal Ser

Explanation:

Amino acids connect like

NH2 -CH(R1) -CO -NH-CH(R2)-CO-.....-NH-CH(Rn)COOH

So, 1st amino acid is N -terminal , and it is Phe.

Last amino acid is C- terminal, and it is Ser.

Calculate the average obtained from the following weighings of the same object. Do not forget to include formulas, units, and th
bazaltina [42]

Answer:

10.4376 g

Explanation:

First we <u>calculate the sum of the weighings</u>:

  • 10.4375 g + 10.4381 g + 10.4373 g + 10.4376 g = 41.7505 g

Then we <u>divide the sum by the number of weighings to calculate the average:</u>

  • Number of weighings = 4
  • Average = Sum of weighings / Number of weighings
  • 41.7505 g / 4 = 10.4376 g

Consider the reaction below:
melisa1 [442]

Answer:

(A) first order reaction

Explanation:

A first order reaction is a type of reaction in which the rate of the reaction depends only on the concentration on one of the reactants. Since A is the only reactant we have, it is right to deduce that this reaction is a first order reaction.

Note: while the order of this reaction is 1, its molecularity is 2. The molecularity of a reaction is the number of moles of reactants that is actually reacting.

(B) is wrong

This is because a zero order reaction is one in which the rate of reaction is not influenced by the concentrations of the reactants and hence remains constant irrespective. Since we were not furnished with this idea in the question, it is only right that we reject this answer.

(C) is wrong.

C is outrightly wrong as we have only one reactant.

(D) is wrong

We have only one reactant.
