Question: 275

1. What is the order of the decomposition of nitramide in water with respect to H⁺?

A. Negative first order
B. One half order
C. First order
D. Second order

Correct Answer: A

Explanation:

A The passage states that if a chemical is raised to the X power, the reaction is X order with respect to that chemical. The rate law can be written as Rate = k[O₂NNH₂][H⁺]^-1, so the reaction is negative first order with respect to H⁺.
