Question

Write the expression for Kc of the following reactions. (2) a) N2(g) + 3H2(g) ⬄ 2NH3(g) b) CaCO3(s) ⬄ CaO(s) + CO2(g)​

Answer 1

Answer:

___________were the kingdoms where the kings were not hereditary.

2. King_______never tolerated any inefficient official.

3.The capital of the Sakyas was___________

4.The people of Magadha raised________crops in a year

5. The head of artisans' association was known as_______

Answer 2

The Kc for the reactions are as follows

a) Kc = $\frac{[NH3]2}{[N2][H2]3}$

b) Kc = [CO₂]

• Kc stands for equilibrium constant.
• It is usually measured in moles per liter.
• It is expressed in the ratio of the product of equilibrium concentrations of each product raised to their respective stoichiometric coefficients over the product of equilibrium concentrations of each reactant raised to their respective stoichiometric coefficients.
• Another important rule is that all the components in solid-state won't be included in the expression for Kc
• Kc gives you an idea about the extent to which the reaction will proceed at a given temperature.
