An industrial chemist 2.00 moles each of h2 and co2 in a 2.00 L container at constant temperature of 800 degree celcuis. this reaction occurs:
H2(g) + CO2(g) --> H2O(g) + CO(g)
when equillibruim is reached, 0.98 mol of co is in the container. Find the vaule of Kc and Kp
A particular coal contains 2.92% sulfur by mass. When this coal is burned, the sulfur is converted into sulfur dioxide gas. The sulfur dioxide gas then reacts with calcium oxide to form solid calcium sulfite
