Explanation:
To find the amount of product that would be formed from two or more reactants, we need to follow the following steps;
- Find the number of moles of the given reactants.
- Then proceed to determine the limiting reactant. The limiting reactant is the one in short supply which determines the extent of the reaction.
- Use the number of moles of the limiting reactant to find the number of moles of the product.
- Then use this number of moles to find the mass of the product
Useful expression:
Mass = number of moles x molar mass
Answer:
The system will change its concentration to shift to a new equilibrium position.
Explanation:
For example in the Haber Process
N2 + 3H2 ⇄ 2NH3
If the pressure is increased the process will move to the right - to have more NH3 and less of the nitrogen and hydrogen.
Calculate the root mean square velocity of nitrogen molecules at 25°C.
