The activation energy of a certain reaction is 65.7 kJ/mol. How many times faster will the reaction occur at 51°C than at 8°C? State the assumptions you need to make in order to perform this calculation. (Select all that apply.) The collision model and the Arrhenius eq...

A certain first-order reaction has a rate constant of 2.75 10-2 s−1 at 20.°C. What is the value of k at 50.°C if Ea = 75.5 kJ/mol? i know to use the ln(k1/k2)= (ea/R)((1/T1)-(1/T2)) but how do i know what T2 is when i only have one temp? there is a b part to the ...

I figured that one out but can smoneoe help me with this one. The activation energy of a certain reaction is 65.7 kJ/mol. How many times faster will the reaction occur at 51°C than at 8°C?

Calculate the fraction of atoms in a sample of argon gas at 365 K that has an energy of 11.0 kJ or greater.
Physics, help!!
How do I get the equation T=2pi(sqrt(m/k)) to the linear equation y=mx+b?

torr
chem
does the temperature it gives have anything to do with the problem?
chem
i just tried that and it is wrong.
chem
is k negative because of the s-1? without making it negative i got 15.21 which seemed more reasonable but when i plugged it in it was wrong
chem
i got 11873 which seems kinda high..?
