but what happens to the concentration of SO2? does it decrease?
chemistry
What happens to the concentration of SO2(g) when the total pressure on the equilibrium reaction 2 SO2(g) + O2(g) <---> 2 SO3(g) is increased (by compression)? I thought it remained the same but that was incorrect.
chemistry
how do I know which side heat is on?
chemistry
Consider the reaction at equilibrium: 2NO2(g) <---> N2O2(g) + O2(g) for which, H = −20.4 kJ · mol−1. If you decrease the temperature of the system, what will occur?
chemistry
Consider the combustion of glucose: C6H12O6(s) + 6O2(g) <---> 6CO2(g) + 6H2O(g) H = −3 kJ/mol Which condition I) Adding more carbon dioxide; II) Performing the reaction in a hotter environment; III) Decreasing the pressure of the system; IV) Adding a reagent that i...
