b) none of the listed answers are correct

c) no valid conclusion can be drawn from the information provided.

d) the activation energy of the reverse reaction is less than that of the forward reaction.

e) the activation energy of the reverse reaction is greater than that of the forward reaction.

e) The activation energy of the reverse reaction is greater than that of the forward reaction.

Explanation:

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.
