What trend does the reactivity of nonmetals show in a periodic table? a. random changes without any trends on the periodic table b. changes according to trends on the periodic table c. increases from left to right across the periodic table d. decreases from left to right across the periodic table

Answer : (C) increasing from left to right across the periodic table.

Explanation :

Reactivity : Reactivity means how an atom is to react with the other substances, likely or strongly. This means how an electrons can be removed easily and how they want to take other atom's electrons badly because it is the interaction or transfer of electrons which is the basis of the chemical reaction.

In non-metals, the reactivity increases as we go from left to right across the periodic table.The Non-metals are those which is usually react by gaining of electrons rather than by the losing of electrons. The more the tendency to gaining electrons, the more reactivity with the non-metals.

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?
