Can you please set up the equations for me to help me solve these questions.:
1) How many collisions per second occur on a container wall with an area of
1.00 cm^2 for a collection of Ar particles at 1.10 atm and 290.1 K?
I think I should use  this equation to answer this question:
  ZW = NAp/(2πMRT )^1/2

2) Determine the wavelength of the most intense electromagnetic radiation
emitted from a furnace at 2500.1 °C.


Also, if you can explanes what do you mean by each variable that would be great.

This will clear up the second part...  Wein's displacement law
