According to le chatelier’s principle, if products are removed from a system at equilibrium, the reaction will

The reaction will move in forward direction.

Explanation:

Le-Chatelier's principle states that , "If a system at equilibrium is subjected to a change (in pressure, temperature or concentration of reactants/products), the system will behave in such a way as to oppose the change i.e, it will either move in forward or backward direction."

If the products are removed from a system at equilibrium then it will tend to produce more products so the reaction will shift to forward direction.

the answer is 3.1 his answer is wrong mines is right

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
