Is the arrehnius equation likely to show up on the DAT?

I still have a month to study but it's an equation I haven't really exercised much or committed to memory.

Just know how Ea and T affect K.

Not likely......but understand what the equation means from a quantitative perspective. In other words....Understand that the rate constant depends on factors such as Activation energy, temperature, and collision frequency. A reaction with a small energy of activation will be fast, hence giving a large rate constant. Slow reactions have high energy of activations with small rate constants. One can plot lnk vs 1/ T in Kelvin and achieve a linear plot. Verify this in any General Chemistry book. The slope of this line allows one to calculate energy of activation. Understanding the theory should be all that you need.

Hope this helps.

Thanks for the input guys! Sounds like reasonable expectations.

Understanding the relationships shouldn't be too bad; I'll have to review it a few good times and maybe find a few problems that touch upon it.

Glad we could help. Keep up the great work!

Good luck in your studies and on the DAT!
