What 2 factors determine whether a collision between reactants is effective

Chemistry
1 answer:
andreyandreev [35.5K]3 years ago
4 0

Answer:

  • The kinetic energy and the orientation of the molecules.

Explanation:

As per the <em>collision theory</em>, in order for the reactants yield the products, the molecules or particles must collide with a kinetic energy greater than or equal to the activation energy, and they must collide in the right orientation for the old bonds can be broken and the new ones formed.

The particles of reactants that collide either with less kinetic energy than the needed or in a different orientation will not drive to formation of new products but will "bounce" without producing any chemical change.

This theory is in agreement with the observations that increasing the concentration of reactants increases the rate of reaction, because more collisions will be occur, such as increasing the temperature also increases the rate of reaction, because the collisions will be more energetic.

Find the volume of an object that has a density 0f 3.14g/mL and a mass of 87.3g
pav-90 [236]

Answer:

<h3>The answer is 27.80 mL</h3>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density}  \\

From the question

mass = 87.3 g

density = 3.14 g/mL

We have

volume =  \frac{87.3}{3.14}  \\  = 27.8025477...

We have the final answer as

<h3>27.80 mL</h3>

Hope this helps you

Monodisperse polyacrylonitrile contains molecules with the general formula -(CH2CHCN)n-, where n is typically greater than 10,00
pentagon [3]

Answer:

7.68 × 10²⁴

Explanation:

Step 1: Calculate the mass of 1 molecule of the monomer CH₂CHCN

We will get the mass of the monomer by adding the masses of the elements.

mCH₂CHCN = 3 × mC + 3 × mH + 1 × mN

mCH₂CHCN = 3 × 12.01 amu + 3 × 1.01 amu + 1 × 14.01 amu = 53.07 amu

Step 2: Convert the mass of the monomer to grams

We will use the conversion factor 1 amu = 1.66 × 10⁻²⁴ g

53.07 amu × 1.66 × 10⁻²⁴ g/1 amu = 8.81 × 10⁻²³ g

Step 3: Calculate "n"

We will divide the mass of the polymer by the mass of the monomer.

n = 676.8 g / 8.81 × 10⁻²³ g = 7.68 × 10²⁴
