Why does the rate of most reactions decrease over time?

Chemistry

hi there

your answer to this is :

When you lower the temperature, the molecules are slower and collide less. That temperature drop lowers the rate of the reaction. that is a greater density of molecules increases the number of collisions. When you decrease the pressure, molecules don't hit each other as often and the rate of reaction decreases.

i hope this helps you  out

<h2>Answer:</h2>

<u>As the reactants are consumed, the rate slows down</u>

<h2>Explanation:</h2>

The rate of chemical reaction depends on the availability (concentration) of participating chemical reagents so as the reactants decrease with passage of time, the rate also decreases. The rate of reaction is directly proportional to the reagent concentration. Another reason is that with the passage of time most often the temperature also goes down hence resulting the slowing down of reaction rate.

As what we can see on the graph of the Boyle's Law, we can imply that volume and pressure are inversely proportional. The gas law furthermore explains that at this condition, the temperature must be held constant. The law can be furthermore be explained using the equation:

Which of the following describes a covalent bond?
Marizza181 [45]

Answer:

D. It is the sharing of electrons between atoms with an electronegativity difference below 1.7

Covalent bonds share electrons, whereas ionic bonds exchange electrons. Covalent bonds have an electronegativity of 0.0-1.7 (0.0-0.3 is a nonpolar covalent bond and 0.3-1.7 is a polar covalent bond). Ionic bonds are bonds that go beyond the electronegativity of 1.7 to 4.0 (1.7-4.0).

The permanent electric dipole moment of the water molecule 1H2O2 is 6.2 * 10-30 C m. What is the maximum possible torque on a wa
stellarik [79]

Answer:

3.1 x 10⁻²¹ Nm

Explanation:  

When placed in an external electric filed, an electric dipole experiences a torque. and this torque is represented mathematically with the equation:

torque (τ) = dipole moment vector (P) x electric field vector (E)

τ = P. E . sin θ

where θ is the angle between the water molecule and the electric field, which in this case is 90° (because this is where the torque is maximum)

τ = 6.2x10⁻³⁰Cm . 5.0x10⁸ N/C . sin90

τ = 6.2x10⁻³⁰Cm . 5.0x10⁸ N/C . 1

solve for τ

τ = 3.1 x 10⁻²¹ Nm

the maximum possible torque on the water molecule is therefore 3.1 x 10⁻²¹ Nm
