A few factors influence the rate of reaction, including :

<em>Temperature</em>. Most reactions increase in rate as temperature increases; most reactions slow down as temperature decreases.

<em>Concentrations of the reactant</em>. Raising the concentration of a substance will increase the speed of the reaction; lowering the concentration of a substance will decrease the speed of the reaction. The limiting reactant is the reactant that is completely used up in a reaction. When this is completely used up, the reaction will stop.

<em>Catalysts</em>. These are substances that speed up the rate of the reaction by lowering the activation energy. If a catalyst is added, the rate of reactions will increase. If a catalyst is removed, the rate of reactions will decrease. Enzymes are biological catalysts used in living things to speed up internal reactions.

<em>Inhibitors</em>. These are substances that slow down the rate of a reaction. If an inhibitor is added to a reaction, its rate will decrease. If an inhibitor is removed from a reaction, its rate will increase.

Thus, the right answer is B. Lowering the concentration of the reactants

How many moles of a gas would occupy 22.4 Liters at 273 K and 1 atm?
Molodets [167]

Answer:

1 mole of a gas would occupy 22.4 Liters at 273 K and 1 atm

Explanation:

An ideal gas is a set of atoms or molecules that move freely without interactions. The pressure exerted by the gas is due to the collisions of the molecules with the walls of the container. The ideal gas behavior is at low pressures, that is, at the limit of zero density. At high pressures the molecules interact and intermolecular forces cause the gas to deviate from ideality.

An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:

P * V = n * R * T

In this case:

  • P= 1 atm
  • V= 22.4 L
  • n= ?
  • R= 0.082 \frac{atm*L}{mol*K}
  • T=273 K

Reemplacing:

1 atm* 22.4 L= n* 0.082 \frac{atm*L}{mol*K} *273 K

Solving:

n=\frac{1 atm* 22.4 L}{0.082 \frac{atm*L}{mol*K} *273 K}

n= 1 mol

Another way to get the same result is by taking the STP conditions into account.

The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C (or 273 K) are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.

75 mL of water is added to a 360 mL solution of acetic acid with a concentration of 0.87 M. Determine the molarity of the new so
kramer

Answer:

The molarity of the new solution is 0.72 M

Explanation:

Step 1: Data given

Volume of the original solution = 360 mL =.360 L

Molarity = 0.87 M

We add 75 mL = 0.075 L

Step 2: Calculate moles

Moles = molarity * volume

Moles = 0.87 M * 0.360 L

Moles = 0.3132 moles

Step 3: Calculate new molarity

The number of moles stays constant

Molarity = moles / volume

Molarity = 0.3132 moles / (0.36+0.075)

Molarity = 0.3132 moles / 0.435 L

Molarity = 0.72 M

The molarity of the new solution is 0.72 M

If an element has 1 valence electrons, how many dots will be in the elements dot diagram?
gayaneshka [121]
The answer is one dot.

The number of dots an element has represented in the diagram, indicates how many valence eletrons( which is the number of electrons in the most exterior energy level of an atom or ion) the element has. So, 1 valence eletron equals one dot.

What does a chemical bond results from a rearrangement of?
Dmitriy789 [7]

Atoms

Explanation:

Chemical bonds results from the rearrangement of atoms in a chemical species.

It deals with the various attractive forces joining chemical species togethe.

  • When atoms are re-arranged, they form chemical bonds that leads to production of new compounds.
  • This is made possible by the exchange or sharing of electrons.
  • The driving force for most interatomic bonding is the tendency to have completely filled outer energy levels like the noble gases.
  • When atoms are re-arranged in compounds they lead to the production of chemical bonds.
