Consider the following reaction that takes place at 1200 °C: H, (g) + CI, (g) + 2HCI (g) Kc = 2.5x10 Hydrogen gas and chlorine gas were added to a reaction vessel at partial temperatures of 2.00 atm and 1.00 atm, respectively. Calculate the total pressure in the flask at equilibrium.
Heating HI(g) at 425 °C causes some of this compound to decompose, forming H2 (g) and I2 (g). Eventually, the amounts of the three species do not change further, the system has reached equilibrium. (At this point, approximately 22% of the HI has decomposed.) What is happening in this system at the molecular level? O H2(g) reacts with I2 (g) to produce HI(g) at the same rate as it decomposes. H2 (g) and I2 (g) molecules collide with HI(g) making the reaction stop. Only part of the HI(g) molecules has enough energy to decompose at this temperature. 5:55 PM FLV 2/22/2020 Type here to search hp ins prt sc delete home f12 f8 f9 f10 f5 f6 f7 14 10 num & backspace lock 23 8. 3 %24
