A researcher collected the data shown to see how the concentration of thiosulfate in water affects the reaction time with hydrochloric acid. Which conclusion can the researcher draw?

A
As concentration increases, reaction time decreases.

B
There is no obvious mathematical relationship.

C
As concentration decreases, reaction time decreases.

D
As concentration increases, reaction time increases.

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.

b. is the answer hoped i
