HCI(g) can be made by the direct reaction of H2 and Cl2 in the presence of light. 3.00 g of H2 and 140 g Cl2 are mixed in a 10.00 L flask at 28.0 C. What are the partial pressures of gases after the reaction has completed. Here is the data you'll need: > Temperature and volume remains constant at 28.0 C > Wavelength of light needed for the reaction is 340 nm
