At 50 C(celcius), Kc = 2.2 x 10^3 for the reaction 3 Fe (s) + 4 H2O (g) ? Fe3O4 (s) + 4 H2 (g) What is the value of Kp at 200oC

for this reaction? A) 8.8 x 103 B) 2.2 x 103 C) 5.5 x 102 D) 3.5 x 104 E) This question cannot be answered with the information provided
At 1050 K, Kp = 0.900 for the following reaction: H2(g) + CO2(g) ? H2O(g) + CO(g) If 0.200 atm of H2 and 0.200 atm of CO2 are admitted into a rigid container and allowed to reach equilibrium, what should the equilibrium partial pressure of CO be (in atm)? [enter number with three decimal places]

In an exothermic equilibrium reaction, increasing the reaction temperature favors the formation of reactants. A) True B) False

The equilibrium-constant expression for a reaction written in one direction is the reciprocal of the one for the reaction written for the reverse direction. A) True B) False

A balloon is filled to a volume of 1.50 L with 3.00 mol of gas at 25 C. with pressure and temperature held constant, what will b
bixtya [17]

Answer:

3.2L

Explanation:

PV=nRT

since pressure and temperature are held constant we have V=nR

R is a constant also,

Thus; \frac{v1}{n1}=\frac{v2}{n2}

v1=1.5L  , n1=3mol, n2=1.4mol

\frac{1.5}{3}=\frac{v2}{1.4}

v2=\frac{1.5}{3}*1.4

v2=3.2L

Elina [12.6K]

Answer:

D

Explanation:

A solid is characterized by structural rigidity and resistance to a force applied to the surface. Unlike a liquid, a solid object does not flow to take on the shape of its container, nor does it expand to fill the entire available volume like a gas. Solids molecules stay close to eachother maintaining its shape meaning it is in a ordered pattern.
