Consider the following mechanism: Cl2 → Cl+ + Cl- Cl- + H2S → HCl + HS- Cl+ + HS- → HCl + S What is the role of Cl+? A. product B. intermediate C. catalyst D. reactant
The rate of a reaction is how quickly the reaction goes to completion. If two reactions have the same amount of reactant, increasing the rate does not increase the amount of product produced, it simply reduces the time that it takes to make the product. Using the internet, research the Reactant concentration factor below that affect the rate of a chemical reaction. 1. Reactant concentration (be very detailed add graphs to explain your details it should be 300 words) Your work should be written in complete sentences, and assume your audience is grade 11 chemistry students who do not understand this unit. Make sure all research is put into your own words!
Consider the following mechanism: NO → N + O O + O3 → 2 O2 O2 + N → NO2 What is the role of O2? A. product only B. intermediate only C. Both intermediate and product D. reactant E. catalyst

If for the reaction a b d e aX → by → 9 the rate law is determined to be r=[X]¹[Y]º the order of the reaction is 0 increasing the concentration of Y will have no effect on the rate increasing the concentration of X will have no effect on the rate increasing the concentration of Y will increase the rate of the reaction there is no way to determine the value of k 9 then
Lab 6 - MOLAR MASS OF VOLATILE LIQUID question: How will the unknown’s reported molar mass be affected in each of the following cases The atmospheric pressure is recorded too high. A small piece of the foil cap was lost before the final mass was measured.
Based on the result from the room temperature experiment (20°C), estimate the time it would take a piece of zinc to completely react in hydrochloric acid at a temperature of 30°C. Remember, as a general rule the rate will double for every 10°C increase in temperature. **Note: the result from the experiment was that it took Zinc 2 minutes and 27 seconds to completely react in hydrochloric acid at room temperature (20°C) a) about 1:20 b) about 0:40 c) about 5:20 d) about 13:30
