An equilibrium constant is not changed by a change in pressure.

True or False

True

Explanation:

Only temperature changes the value of the equilibrium constant.

For any system in equilibrium, the molar concentration of all the species on the right side are related to the molar concentration of the species on the left side by the equilibrium constant .

The equilibrium constant is a constant at a given temperature. It is temperature dependent.A shift in equilibrium as a result of temperature change is actually a change in the value of the equilibrium constant.

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.

You would be correct, boiling water does disinfect contamination.    the property of disinfecting means to kill  germs, bacteria and other pathogens or contamination  that might cause an infection or cause a person to become sickly. a couple methods of disinfecting are using soap, other cleaning supplies or by simply "boiling" the contaminate.  the reason why boiling water disinfects certain attributes is because some cells cannot survive the heat and pressure.
