Which reaction (forward or reverse) is endothermic?

Question 1
1.
What are the reactants in the forward (exothermic) reaction?
Question 2
2.
What are the reactants in the reverse (endothermic) reaction?
Question 3
3.
When the reaction achieves equilibrium the rate of the forward reaction is the same as the rate of the reverse reaction. (both reactions are going at the same speed)
Question 4
4.
The concentration of the reactants equals (is the same as) the concentration of the products when a reaction is at equilibrium
There are fewer N2 molecules that can have effective collisions with H2 molecules to form less NH3molecules.
The rate of reverse reaction will temporarily increase to try to achieve equilibrium (balance) again
Forward
Reverse
Question 8
8.
What is the ratio of moles of Cl-1 ions to CoCl4-2 based on the balanced chemical equation?
Question 9
9.
Use the mole ratio from question 1 to calculate the amount of moles CoCl4-2 that would form if we added 1 mole of Cl-1 to this reaction?
Question 10
10.
Use the molar mass of CoCl4-2 to calculate the mass of CoCl4-2 formed. (Hint: Add the atomic masses together to get your molar mass. Find your mass in grams by multiplying the moles from question 2 by the molar mass. Mols * Molar mass)
