A 2.0-mol sample of an ideal gas occupies 10.0 L at a certain instant when its temperature is 300 K. The volume remains fixed while the temperature is increasing at a rate of 4.0 K·min−1. Using R=0.0821L·atm·mol−1·K−1, what is the instantaneous rate of change of the gas’s pressure at that instant?
a) 0.33atm⋅min−1
b) 0.066atm⋅min−1
c) 0.016atm⋅min−1
d) 0.033atm⋅min−1
