Use the exponential term in the Arrhenius equation to explain how temperature affects reaction rate.
WINSTONCH [101]

The Arrhenius equation describes the relation between the rate of reaction and temperature for many physical and chemical reactions

It is an expression that provides a relationship between the rate constant (of a chemical reaction), the absolute temperature.

The Arrhenius equation,

k = zpe^{\frac{- Ea}{RT} }, where

k is the rate constant,

z is the collision factor,

p is the steric factor,

Ea is the activation energy,

R = 8.3245 \frac{J}{mol. K} is the ideal gas constant, and,

T is the temperature.

The activation energy by definition, is the minimum energy (or threshold energy) required for two particles of reactants upon collision to form products.

The Arrhenius equation could also be written as:

⇒ k = Ae\frac{-Ea}{RT}, where

⇒ A = zp, the Arrhenius factor.

Taking the neutral logarithm of both parties, we get:

⇒ In k = \frac{-Ea}{RT}\frac{(1)}{(T)} + In A,

Assuming that, A is independent of temperature, when T is increased, the equilibrium constant k will also increase and therefore, the rate of the reaction will also increase.

Please select the word from the list that best fits the definition Vibrations that move through the ground carrying the energy r
ZanzabumX [31]
<h2>Answer : Seismic Waves.</h2><h2 /><h3>Explanation : </h3><h3>Vibrations that move through the ground carrying the energy released during an earthquake are called seismic waves.</h3>

Seismic waves are waves of energy which usually travels through the Earth's layers, and as a result release the energy during earthquakes, volcanic eruptions, magma movement, large landslides or large man-made explosions. It is mainly measured through a special instrument called as seismometer and the graph obtained is called as seismograph.

What is the law of conservation and what happens when two substances at different temperatures come into contact.
insens350 [35]

Answer:

- Both energy and matter cannot be neither created nor destroyed.

- An equilibrium temperature will be reached.

Explanation:

Hello,

In this case, the law of conservation is applied to both matter and energy, and it states that both energy and matter cannot be neither created nor destroyed. Specifically, in chemical reactions, it states that in closed systems, the mass of the reactants equals the mass of the products even when the number of moles change. Moreover, for energy, if two substances at different temperatures come into contact, the hot one will cool down and the cold one will heat up until an equilibrium temperature so the energy lost by the hot one is gained by the cold one, which accounts for the transformation of energy.

Best regards.
