Consider the reaction below 2SO2(g) + O2(g) ⇌ 2SO3(g) At 1000 K the equilibrium pressures of the three gases in one mixture were

Vsevolod [243]

Answer: $K_p$ for the reaction is 3.45

Explanation:

The balanced chemical reaction is:

$2SO_2(g)+O_2(g)\rightleftharpoons 2SO_3(g)$

At eqm. 0.562 atm 0.101 atm 0.332 atm

As we are given that:

The expression of $K_p$ for above equation follows:

$K_p=\frac{(p_{SO_3})^2}{(p_{SO_2})^2\times p_{O_2}}$

Putting values in above equation, we get:

$K_p=\frac{(0.332)^2}{(0.562)^2\times 0.101}=3.45$

The value of $K_p$ for the reaction is 3.45

In the reaction A+B - C+D, if element B is in excess, then-

SOVA2 [1]

Answer:

Explanation:

Determining the Limiting Reagent

One reactant (A) is chosen, and the balanced chemical equation is used to determine the amount of the other reactant (B) necessary to react with A. If the amount of B actually present exceeds the amount required, then B is in excess, and A is the limiting reagent.
