to get the original -7.6 answer i used the two lowest two points here and subtracted:
x y
3.50E-03 -11.7
3.14E-03 -8.96
3.28E-03 -9.75
(-11.7) - (-8.96)
--------------------------
(3.50x10^-3)-(3.14 x10^-3)
= -7.6111x10^3
to calculate Ea i solved for slope and i got -7.6111x10^3
so i did this for Ea:
7.61x10^3 x 8.314/mole= 63.3 KJ/Mol
but someone told me im missing the number 2.30? that i have to mulitply
(2.30)(8.314)(7.61x10^3)=?
which is right?
