Imagine that you run this experiment and that the initial change in pressure is 0.0023 atm/s. what is the initial reaction rate? the temperature of the water bath is 20.0 oc.

Explanation:

Concentration ;

The reaction see a change in pressure per second. By the ideal gas law, this quantity would correspond to a change in concentration, of

where the ideal gas constant .

By definition,

Therefore, for this particular reaction

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

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
