C- K4O8 and K2O4
K4O8/4 =KO2
K2O4/2 =KO2
False they still can as the shockwaves can be very strong
The given equilibrium reaction is,

According to Le Chatelier's principle states that when a system in equilibrium is disturbed by varying conditions like concentration, pressure, and temperature of the system, the system tries to counter act the affect by shifting the equilibrium towards the required side.
When
is removed from the system, the concentration of chlorine (
) decreases, the equilibrium is disturbed. So, the system tries to re-establish the equilibrium by moving in that direction which produces more of chlorine, that is towards the reactant side.
The correct answer would be: 1. reaction would go to the left, making more "reactants"
