Calculate the value of ln(k1/k2) where k1 and k2 correspond to the rate constants at the initial and the final temperatures as defined in part A.

Hi,

The gas-phase reaction of NO with F2 to form NOF and F has an activation energy of Ea = 6.30 kJ/mol and a frequency factor of A = 6.00×108 M−1⋅s−1 . The reaction is believed to be bimolecular:

NO(g)+F2(g)→NOF(g)+F(g).What is the rate constant at 685 ∘C ?

Good day,


A certain first-order reaction has a rate constant of 4.00×10−3 s−1. How long will it take for the reactant concentration to drop to 18 of its initial value

Consider the reaction

2H3PO4→P2O5+3H2O


Using the information in the following table, calculate the average rate of formation of P2O5 between 10.0 and 40.0 s.


Time (s) 0 10.0 20.0 30.0 40.0 50.0

[P2O5] (M)0 2.30×10−3 5.30×10−3 7.10×10−3 8.30×10−3 8.90×10−3
