The frequency factor and activation energy for a chemical reaction are A = 9.33 x 10–12 cm3/(molecule·s) and Ea = 17.2 kJ/mol at 388.8 K, respectively. Determine the rate constant for this reaction at 388.8 K.

Now that the first three steps have been explained, identify the next three steps, in order. calculate the magnitude of r sum vector components calculate a and b magnitudes calculate the direction of r, calculate x, y components step 4 step 5 step 6

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
