A student observes a reaction where the reaction profile shows products at lower energy than reactants. This means the reaction is:
The Maxwell–Boltzmann distribution curve at a higher temperature compared with a lower temperature is characterized by:
When two reactant molecules need a specific alignment to react, what term describes the proportion of collisions that have the correct orientation?
Which factor changes the proportion of collisions having energy equal to or greater than the activation energy most directly?
How does a catalyst increase the rate of a reaction?
Which change will increase the number of successful collisions per second in a solution?
Which of these changes would increase the fraction of molecules with energy = activation energy?
Which quantity is called the activation energy of a reaction?
A student measures rate as volume of gas produced per second. Which change to the apparatus gives a more accurate measurement of small volumes collected?
In a reaction A + B ? products, which effect does increasing the concentration of A have (all else constant)?
How does increasing pressure affect the rate of reaction for gases when other conditions are constant?
