starting with pure NO2 (g) at a pressure of 0.5 atm , the total pressure inside the reaction vessel when
2NO2 (g) < ---> 2NO (g) + O2 reahes equilibrim is 0.674 atm , calculate the eauilibrim partial pressure of NO2

answer is ; 0.152



I2 <---> 2I(g), at 1000k , the equiliriem cpnstant kc is 3.80 * 10^-5
suppose u start with 0.0456 of I2 in a 2.30 L flask at 1000k whAT R THE CONCENTRATIONS OF THE GASES AT THE EQUILIBRIM?

what iz za detailed answer . plz ?
