Express the equilibrium constant for the following reaction. p4o10(s) ↔ p4(s) + 5 o2(g)k = [p4][o2]^5/[p4o10]k = [o2]^5k = [p4o10]/[p4][o2]^1/5k = [o2]^-5k = [p4o10]/[p4][o2]^5

Answer : The correct expression for equilibrium constant will be,

Explanation :

Equilibrium constant : It is defined as the equilibrium constant. It is defined as the ratio of concentration of products to the concentration of reactants.

The equilibrium expression for the reaction is determined by multiplying the concentrations of products and divided by the concentrations of the reactants and each concentration is raised to the power that is equal to the coefficient in the balanced reaction.

As we know that the concentrations of pure solids are constant that is they do not change. Thus, they are not included in the equilibrium expression.

The given equilibrium reaction is,

The expression of will be,

Therefore, the correct expression for equilibrium constant will be,

what is the volume occupied by 40 grams of argon gas (ar) at standard conditions? what volume, in liters, is occupied by 1.5 x 1023 

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
