WILL MARK BRAINLIEST IF CORRECT Under which temperature and pressure conditions will the volume of a gas be greatest?

a
T = 200K and P = 0.5 atm
b
T = 200 K and P = 3 atm
c
T = 400K and P = 0.5 atm
d
T = 400K and P = 3 atm

Acertain reaction has a activation energy of 54.0 kj/mol. as the temperature is increased from 22c to a higher temperature, the rate constant increases by a factor of 7.00. calculate the higher temperature. c (report only numerical answer)
