Could you tell me how to solve this equation
serjio:
The frequency factor is 6.31 x 108 M s-1 and the activation energy is 10 kJ/mol for the gas phase reaction: NO(g)+ O3(g)->NO2(g)+O2(g). Calculate the rate constant for this reaction at 370 K.
I try to use k= A e ^Ea/RT but it always wrong. Can anyone help me about this :'( :'(
MNIO:
can you show your work?
do you have consistent units?
do you have a set of choices to pick from for answers?
Enthalpy:
I doubt about the "+" in the exponential.
You should develop an intuition for that. Learning formulas doesn't work, you must re-establish and double-check every time whether + or -, * or /, and so on.
The activation energy slows down the reaction. So could the "+" possibly be correct?
MNIO:
enthalpy...
I usually write the arrhenius equation as
k = Ao * exp(-Ea / RT)
regardless, I was hoping that Serjio was going to respond and show us his math with how he handled (or missed) that +/- term. But he seems to have fled. Too bad.
