CORRECT (GRADED A+)
At 25 °C, Kc = 7.0 x 1025 for the reaction:
2SO2(g) + O2(g) = (2SO3)(g)
What is the value of Kc for the reaction:
SO3(g) = So2(g) + 1/2 O2 (g) - ANSWER✔✔ kc = 1.2 x 10^-13
When a system [such as the reaction of CO2 (g) with H2 (g) to produce CO (g) and
H2O (g)] reaches a state of equilibrium, - ANSWER✔✔ the rates of the forward
and reverse reactions are equal.
A chemical system is considered to have reached dynamic equilibrium when? -
ANSWER✔✔ the rate of production of each of the products is equal to the rate of
their consumption by the reverse reaction.
Suppose for the reaction A B the value of Q is less than Kc. Which way does the
reaction have to proceed to reach equilibrium — in the forward or reverse
direction? - ANSWER✔✔ Forward, because more products and less reactants are
needed to reach equilibrium.
One possible way of removing NO from the exhaust of a gasoline engine is to
cause it to react with CO in the presence of a suitable catalyst.
2NO(g) + 2CO(g) N2(g) + 2CO2(g)
At 300 ºC, the reaction has a Kc = 2.2 × 1059.
What is Kp at 300 ºC? - ANSWER✔✔ Kp = 4.7 x 10^57
