The value of the rate constant for a gas phase reaction can be changed by increasing the A. temperature of the reaction vessel. B. volume of the reaction vessel. C. pressure of the reactant. D. amount of product.

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.
