A particular reaction has an activation energy of 51.6kJ/mol-rxn. How much faster is the reaction at 50 degrees C versus 25degrees C?
I do not know how to start this!
I think we've gone over this before. You start by substituting into the Arrhenius equation. Ea goes in in J/mol (not kJ/mol) and you change T to kelvin.
So the equation I use is ln k = a + (-ea/rt) correct?
I would use ln(k2/k1) = (Ea/R)(1/T1 - 1/T2)
