A system in equilibrium contains $$I_{2_(g)}\ \text{and} \ I_{(g)}$$ under pressures $$P_1=0,21 \,\text{atm. and}\ P_2=0,23 \,\text{atm.}$$ While its temperature remains constant, we reduce the … system's volume to half its original value. I have to determine $P_1'$ when the system's equilibrium is reestablished. I know I can calculate $K_p$ and I know I somehow have to use $PV =NRT$, but from …
