Question

The equilibrium constant could change when: the temperature of the reaction changes the amount of reactants is higher than the products the amount of products is higher than the reactants the amount of products increases the amount of products decreases A chemical equilibrium may be established: finding Q at any time starting with only reactants, only products or any amount of reactants or products finding the concentration of reactants and products before the reaction starts knowing the rate of the forward reaction knowing the rate of the reverse reaction In the equation: A + B C it is incorrect: K_eq = kf/k tau K_eq = [C]/([A][B]) K_eq is reached when kf = k tau K_eq is reached when the rate_forward = rate_reverse (K_eq)^-1 = ([A][B])/[C] if K_eq = (K_eql)^2 and K_eql: [P][Q]/[R] then K_eq is: [R]/[P][Q] [P]^2[Q]^2/[R] [R]^3/[P]^3[Q]^3 [P]^2[Q]^2/[R]^2 [R]^2/[P]^2[Q]^2 the equilibrium constant for the formation of hydrogen sulfide from hydrogen and sulfur is 0.25 at a certain temperature. H_2(g) + S(g) H_2S(g) the reaction favors the formation of products the reaction won't reach the equilibrium the reaction doesn't favors the formation of reactants the equilibrium lies to the right the reaction favors the formation of reactants

Explanation / Answer

13.

Equilibrium constant changes when the temperature of the reaction changes.

14.

Finding reaction quotient (Q) at any time.

15.

option "c" is incorrect because, equilibrium is reached only when rate of forward reaction is equal to rate of backward reaction

16.

option "D" is correct

17.

The reaction favours the formation of products, because

equilibrium constant is lessthan 1 i.e., the concentration of reactants are more than products. So the reaction favors the formation of products.
