For a reaction
Hydrogen is used as a rocket fuel because it is very light and reacts explosively and completely with oxygen. For the combustion
reaction
aA + bB = cC + dD
2H2(g) + O2(g) = 2H2O(g)
the equilibrium constant K is defined as the ratio of
products to reactants at equilibrium:
what is the likely magnitude of the equilibrium constant K?
• View Available Hint(s)
K =
[A]°[B]*
OK< 10 3
Because K represents the ratio of products to reactants,
the magnitude of K is an indicator of the levels of
products and reactants present when the reaction is at
equilibrium. Some chemical reactions proceed almost
fully to product, whereas other chemicals hardly react
with each other at all, or react so as to have significant
amounts of both reactants and products at equilibrium.
