Question

the rate constant for a the reaction is 1.4 × 10¹¹ dm³ mol-¹ s-¹ calculate the half life and of this reaction is initial concentration of the reactant is 0.1 M​

Answer 1

Explanation:

Solution :

Let the rate equation for the reaction be , <br> rate =<br> where , k = rate constant , n = order of reaction <br> [A] = concentration of reactant <br> given ,<br>mol<br>mol<br>mol<br><br><br> Divide (i) by (ii) <br><br>Order of reaction = 3 

this is a kind of a formula you can solve by doing this

Answer 2

The specific rate constant (k) is the proportionality constant relating the rate of the reaction to the concentrations of reactants. The rate law and the specific rate constant for any chemical reaction must be determined experimentally. The value of the rate constant is temperature dependent.
