Imagine that a chemist puts 6.40 mol each of C3H8 and O2 in a 1.00-L container at constant temperature of 289 °C. This reaction occurs:
C3H8(g) + 5O2(g) ⇄ 3CO2(g) + 4H2O(g)
When equilibrium is reached, 0.411 mol of CO2 is in the container. Find the value of Keq for the reaction.
please give thumbs up to my
answer as I am in very need of that do comment for any of your
doubt
