What would cause the equilibrium to shift left in this reaction?
Lilit [14]

As per Le Chatelier's principle, if the equilibrium of a system is disturbed by changes in temperature, pressure, concentration etc then it will shift in a direction to undo the effect of the induced change.

The given reaction is:

CO + 3H2 ↔ CH4 + H2O

In this case, if the rate of the forward reaction is increased then more of the reactants get converted into products i.e. concentration of reactants decreases. In order to undo this change, the equilibrium will shift in a direction to produce more reactants i.e. to the left.

Ans: B)  faster rate of forward reaction

How does an enzyme affect a chemical reaction?
katen-ka-za [31]
An enzyme can affect a chemical reaction by bringing the reactant closer together - chemical bonds may be weakened, and reactions will happen faster than without a catalyst. The energy can also be lowered, which means reactions will proceed at a lower temperature, light presence, etc.
