How many liters of carbon dioxide can be produced if 37.8 grams of carbon disulfide react with excess oxygen gas at 28.85 degree
alekssr [168]
37.8 grams of CS2 equals to 37.8/76=0.5 mole. So the products have 0.5 mole CO2 which is 11.2 liters at STP. So according to the gas law, the volume at given condition is 12.4 liters. So the answer should be 12.2 liters.

A reaction mixture at 175 k initially contains 522 torr of no and 421 torr of o2. at equilibrium, the total pressure in the reac
zzz [600]
The chemical equation would be:

2NO(g) + O2(g) --> 2NO2 (g) 

<span>At equilibrium state, the partial pressure of the gases would be as follows : </span>

<span>NO = 522 - 2x </span>

<span>O2 = 421 - x </span>

<span>NO2 = 2x </span>
<span>- - - - - - - - - - - - -</span>
<span>943 - x = 748 </span>

<span>x = 195</span>

Calculating for Kp,

<span>Kp = (NO2)^2/ ((NO)^2 * (O2)) </span>

<span>Kp = (2 * 195)^2/ ((522 - 2 * 195)^2 * (421 - 195)) </span>

<span>Kp = 0.0386 </span>
