15-7 Zero Order Reactions

Consider the zero order reaction

1. The rate of a zero-order-reaction is dependent on which of the followings:
1. Reactant
2. Product
3. Both
4. Neither

2. What is the rate constant if it takes 60 second for a 0.50 M of the ammonia gas to decompose to 0.25M?

3. How long does it take for 0.50M of the ammonia gas to decompose to 0.10M?

4. How long does it take for the reactant in question 3 to decompose to 25%?

5. How long does it take for 25% of the reactant in question 3 to be consumed?

6. What is [NH₃] of a 0.80M [NH₃] solution after 3 minutes?

7. Calculate the initial [NH₃] if [NH₃] =0.005M after 10 minutes?
