Answer the following questions True or False. Write “True” or “False” in the blank. 1._________ The rate constant changes if the concentrations of the reactant change. 2._________ If the concentration of a reactant changes, the rate of the reaction always changes. 3._________ The coefficients of the overall reaction tell us the order for each reactant. 4._________ The half-life for a first order reaction does not depend on the initial concentration. 5._________ If the rate of a reaction over a long time period is –0.342 M/min, the reaction could go faster or slower during the time period.

Solutions

Expert Solution

1._________ The rate constant changes if the concentrations of the reactant change.

Answer: False

Rate constant doesn’t depend on concentration. It depends on temperature

2._________ If the concentration of a reactant changes, the rate of the reaction always changes.

Answer: False

Rate will not change for changing concentration of those reactants whose order is 0

3._________ The coefficients of the overall reaction tell us the order for each reactant.

Answer: false

Elementary steps are required or rate law is required to predict the individual order

4._________ The half-life for a first order reaction does not depend on the initial concentration.

Answer: true

half life for 1st order reaction is 0.693/K
