Yes
No
a) The rate constant (k)?
b) The reaction rate?
c) The activation energy (Ea)?
d) The equilibrium constant?
e) The rate law?
B. For the equilibrium CO(g) + 3H2(g) CH4(g) + H2O(g), H = -206kJ/mol.
What will be the effect on the position of equilibrium caused by the following? Will the equilibrium shift to the left (in favor of reactants), to the right (in favor of products), or will there be no change? shift in equilibrium
