Question

Which of the following is true for a dynamic equilibrium The concentrations of ractants and products are equal. The forward and reverse reactions occur at the same rat. The concentrations of reactants and products remain constant over time. Answers a and b are both correct. Answers b and c are both correct. The value of the equilibrium constant for the following reaction is 3.4 times 10^5. 2A + B rightarrow 2C + 4D What is the value of the equilibrium constant for teh reaction below C + 2D rightarrow A + 1/2B K = 2.9 times 10^-6 K = 1.7 times 10^-3 K = 8.7 times 10^-12 K = 5.8 times 10^2 K = 1.2 times 10^11 At a high temperature, the equilibrium partial pressures of N^2, O^2 and NO are as follows: N^2 = 0.36 atm, O _2 = 0.68 atm, and NO = 0.020 atm. What is the value of the equilibrium constant, Kp N^2(g) + O^2(g) rightarrow 2NO(g) 1.6 times 10^-3 12 8.2 times 10^-2 6.1 times 10^2 1.9 times 10^-2

Explanation / Answer

1)

b and c are true. The dynamicc equlibrium has concnetrations interacting between each other and both will not change iwth respect of time (therefore, equilibrium)

2)

This is divided by 2 and inverted; therefore

Knew = (1/K)^(1/2) = (1/(3.4*10^5))^0.5 = 0.00171498585

K = 0.00171498585

3)

Kp = NO^2 / N2O2

Kp = (0.02^2)/(0.36*0.68 ) = 0.00163398692 anser is a
