Select all that apply.When the products of a reaction are hotter than the reactants
andrezito [222]
When the products of a reaction are hotter than the reactants, an exothermic reaction is happening. An exothermic reaction is a reaction that releases energy to the surroundings. The energy released should be more than what is absorbed in order to maintain the reaction.

A reaction that is second-order in one reactant has a rate constant of 1 × 10–2 L/mol · s. If the initial concentration of the r
Harlamova29_29 [7]

Answer : It take time for the concentration to become 0.180 mol/L will be, 277.8 s

Explanation :

The integrated rate law equation for second order reaction follows:

k=\frac{1}{t}\left (\frac{1}{[A]}-\frac{1}{[A]_o}\right)

where,

k = rate constant = 1\times 10^{-2}mol/L.s

t = time taken  = ?

[A] = concentration of substance after time 't' = 0.180 mol/L

[A]_o = Initial concentration = 0.360 mol/L

Putting values in above equation, we get:

1\times 10^{-2}=\frac{1}{t}\left (\frac{1}{0.180}-\frac{1}{0.360}\right)

t=277.8s

Hence, it take time for the concentration to become 0.180 mol/L will be, 277.8 s
