The typical speed of a reaction releases gas every twenty seconds for two minutes. The chart lists four substances that were added to the reaction at different times.

Question

Which statement best summarizes the chart?

Substances W and Y are catalysts, and substances X and Z are inhibitors.
Substance W is an inhibitor, and substances X, Y, and Z are catalysts.
Substances W and Z are inhibitors, and substances X and Y are catalysts.
Substance X is a catalyst, and substances W, Y, and Z are inhibitors.

Answer 1

To determine which statement best summarizes the chart, we would need to analyze the data presented in the chart regarding the effects of the substances on the reaction rate. Since the chart isn't provided, I can guide you on how to determine the best summary based on the behavior of the substances.

1. Identify the role of each substance:

   • If adding a substance increases the reaction rate or the frequency of gas release, it's likely a catalyst.
   • If it decreases the reaction rate or delays gas release, it functions as an inhibitor.

2. Analyze each statement:

   • Substances W and Y are catalysts, and substances X and Z are inhibitors: This means W and Y speed up the reaction while X and Z slow it down.
   • Substance W is an inhibitor, and substances X, Y, and Z are catalysts: Here, W slows the reaction, and X, Y, and Z speed it up.
   • Substances W and Z are inhibitors, and substances X and Y are catalysts: This indicates that W and Z slow the reaction, while X and Y enhance it.
   • Substance X is a catalyst, and substances W, Y, and Z are inhibitors: This means X speeds up the reaction, while the others slow it down.

If you analyze the chart and determine how each substance affects the reaction rate, choose the statement that corresponds with that observed data. Without the actual chart data, I cannot provide a definitive answer. If you can share specifics from the chart, I'd be glad to help you evaluate it further!
