At constant temperature, why can increasing reactant concentration increase reaction rate?
What does a rate law show?
How do chemists usually determine a rate law?
In Rate = k[A]ᵐ[B]ⁿ, what do [A] and [B] represent?
In Rate = k[A]ᵐ[B]ⁿ, what is k?
What is the reaction order with respect to a reactant?
For Rate = k[A]²[B], what is the order with respect to A?
For Rate = k[A][B]², what is the overall reaction order?
A reaction is zero order with respect to A. If only [A] doubles, what happens to rate? Keep temperature constant.
A reaction is first order with respect to A. If only [A] doubles, what happens to rate? Keep temperature constant.
For Rate = k[A]²[B], [A] doubles while [B] and temperature stay constant. What is the rate multiplier?
For Rate = k[A][B]², [B] doubles while [A] and temperature stay constant. What is the rate multiplier?
Which statement about reaction orders is correct?
What is a reaction mechanism?
Step 1: NO₂ + NO₂ → NO₃ + NO. Step 2: NO₃ + CO → NO₂ + CO₂. Which is the overall equation?
Step 1: NO₂ + NO₂ → NO₃ + NO. Step 2: NO₃ + CO → NO₂ + CO₂. Which species is the intermediate?
Why is NO₃ an intermediate in this mechanism? Step 1 forms NO₃; step 2 uses it.
A production line has three consecutive stages: 12 items/min, 3 items/min and 10 items/min. Which stage limits the output?
A line has stages of 12, 3 and 10 items/min. Would speeding up Stage 1 alone remove the bottleneck at Stage 2?
A simple mechanism has a slow first step and a fast second step. Which step determines the overall rate?
