Is there an algebraic reason why 1/t is proportional to initial rate? [closed]
Why is the initial rate of a reaction proportional to $1/t$ and why would this be according to our rate laws? Could a derivation of this been shown and what would this mean?

Is order defined for a reaction which does not follow power law dependence?
As per my knowledge , order of a reaction is the sum of exponents of all the terms in rate law of the reaction
But reaction which do not follow power law dependence , for example , formation of HBr , ...

Is this statement valid for reactions of all orders? [duplicate]
My textbook (not an international standard) states that for the first order reactions only
The quantity of reactant remaining after $n$ half lives is
$$A_n = \frac{A_0}{2^n},$$
where $A_0$ is the ...

Second order reaction with different reactants
In a laser photolysis reaction $\ce{C6H5NH2}$ $(C_0 = \pu{60 µM})$ is oxidized to its radical cation. The disappearance of the cation can follow three pathways: (1) Dimerzing of the cation, (2) ...

Can iodine replace other halogen as well?
While reading about halogen family I encountered the reaction:
$$\ce{NaClO3 + I2 -> NaIO3 + Cl2}$$
I know that that the oxidizing tendency of halogens decreases down the group, so I think that the ...

Reaction order of a reaction with catalyst
I am given the following
$\ce{H2O2 -> H2O + 1/2 O2}$ (catalysed by $\ce{KI}$)
There are two solutions. $[\ce{H2O2}]$ is the same in both solutions but $[\ce{I-}]$ is $\pu{0.01M}$ and $\pu{0.005M}$,...

How is the Rate law of a reaction measured?
What is the Rate law of the reaction below?
$$\ce{4 HBr + O2 -> 2 H2O + 2 Br2}$$
How do we approach finding the rate law of a reaction? Can this be found out only through experiments?
