How is the effect of concentration changes on the reaction rate seen in the rate law?
A. The effect of concentration changes on the rate constant affects
the reaction rate.
O B. A change in concentration of a reactant would change the
exponent of that reactant.
O C. The rate law does not show how concentration changes would
affect the reaction rate.
D. The exponents determine how much concentration changes affect
the reaction rate.

D. The exponents determine how much concentration changes affect

the reaction rate.

Explanation:

took class

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
