One mole of H2 gas is contained in a box...

One mole of `H_2` gas is contained in a box of volume `V = 1.00 m^3` at `T = 300 K`. The gas is heated to a temperature of T = 3000K and the gas gets converted to a gas of hydrogen atoms. The final pressure would be (considering all gases of be ideal)

A

same as the pressure initially

B

2 times the pressure initially

C

10 times the pressure initially

D

20 times the pressure initially.
