<u>Answer:</u> The rate law for the given chemical equation is ![\text{Rate}=k[Li][NaCl]](https://tex.z-dn.net/?f=%5Ctext%7BRate%7D%3Dk%5BLi%5D%5BNaCl%5D)
<u>Explanation:</u>
Rate law is defined as the expression that expresses the rate of the reaction in terms of the molar concentration of all the reactants each term raised to the power their stoichiometric coefficient in the given balanced chemical equation.
For the given balanced chemical equation:
![Li+NaCl\rightleftharpoons Na+LiCl](https://tex.z-dn.net/?f=Li%2BNaCl%5Crightleftharpoons%20Na%2BLiCl)
Rate law expression for the reaction:
![\text{Rate}=k[Li][NaCl]](https://tex.z-dn.net/?f=%5Ctext%7BRate%7D%3Dk%5BLi%5D%5BNaCl%5D)
Order with respect to Li = 1
Order with respect to NaCl = 1
Hence, the rate law for the given chemical equation is ![\text{Rate}=k[Li][NaCl]](https://tex.z-dn.net/?f=%5Ctext%7BRate%7D%3Dk%5BLi%5D%5BNaCl%5D)
<h3>Answer:</h3><h3>Law of inertia, also called Newton's first law, postulate in physics that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force</h3>
Answer:
Explanation:
You can infere the units of the rate constant for an <em>overall order 2 reaction </em>departing from the simplified case of a two identical reactants combined in a single elementary step:
- A + A → Products (single elementary step equation)
For that equation the differenttial form of the rate of reaction is:
- r = - d [A] / dt = K [A]²
The units of [A] are M¹ (i.e. M), and the units of - d [A] / dt are M¹ s⁻¹ . . . ( M stands for molar concentration)
Substituting the unis on both sides of the rate equation you get:
Solving for K:
- K = M¹ s⁻¹ M⁻² = M⁻¹ s⁻¹, which is the final result.
As temperature rises, molecules tend to move at a faster rate meaning that the energy has increased.
