What happens to a system at equilibrium when you add a catalyst?
Both the forward and reverse reactions will speed up so there will be no change overall!
In an Endothermic reaction where does the energy for the reaction come from.
What is the surroundings

These metals in order of increasing reactivity: Pb, Ni, Zn, Ag, Sn, Cu, Mg, Fe
What is Ag, Cu, Pb, Sn, Ni, Fe, Zn, and Mg
N2 + 3H2 <---> 2NH3 Initially, 12 mol NH3 are put in a 2L flask. At equilibrium, the concentration of N2 is 1 M. What is the Keq?
The equilibrium constant is 0.59
Use the thermochemical equations shown below to determine the enthalpy for the reaction:
H₂O → H₂ + ½O₂
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O ΔH= -4440kJ
C + O₂ → CO2 ΔH= -788kJ
3C + 4H₂ → C₃H₈ ΔH= -208kJ
H₂O → H₂ + ½O₂ ΔH= 571kJ
This gas is released when a acid reacts with a metal
What is Hydrogen
