Thermal energy is the energy that comes from heat. This heat is generated by the movement of tiny particles within an object. The faster these particles move, the more heat is generated.

Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another, and the transfer or flow due to the difference in temperature between the two objects is called heat.

The kinetic temperature is the variable needed for subjects like heat transfer, because it is the translational kinetic energy which leads to energy transfer from a hot area (larger kinetic temperature, higher molecular speeds) to a cold area (lower molecular speeds) in direct collisional transfer.

The dimerization of butadiene 2C4H61 g2h C8H121 g2 was studied at 500. K, and the following data were obtained: Time (s) [C4H6]

ivanzaharov [21]

Answer:

Rate law: $k[C_4H_6]^2$

Integrated Rate Law: $\frac{1}{[C_4H_6]}=\frac{1}{[C_4H_6]_0}+kt$

$k = 1.4 \times 10^{-2}$

Explanation:

We can see that the graph of time is linear compared to $\frac{1}{[C_4H_6]}$ and the reaction is second order hence we get the rate law from $k[A]^n$ .

The integrated rate law for second order is $\frac{1}{[A]}=\frac{1}{[A]_0} +kt$ where A is $C_4H_6$ .

The slope of the graph $\frac{1}{[C_4H_6]}$ w.r.t time is equal to k. The slope of the graph from the table is 0.014 which is equal to k.
