What is the rate constant for this reaction (1/sec) ?

Question

At a certain temperature the reaction

2N2O5 → 4NO2 + O2

is a first order reaction with t1/2 = 115.0 sec

Answer 1

rate constant k= 0.693/half life time { this is for the first order reactions only}
k= 0.693/115
Thats it

Answer 2

you're complicated cost of reaction with place of equilibrium. they don't seem to be the comparable ingredient. improve of rigidity and improve of temperature continually improve the cost of a gasoline area reaction. If the reaction is reversible the situation of equilibrium could exchange in the two course however the cost of reaction will continually improve. in reality the reaction you coach isn't reversible so elimination of a product will have not have been given any result. A is genuine.

Answer 3

k=ln(2)/t1/2

now plug in your numbers and you're done
