Label each statement as True or False. For false answers, cross out what is false and correct the statement so that it is true.

T or F

a.Reactions are faster at a higher temperature because activation energies are lower.
b.It is possible to change the rate constant by changing the temperature.
c.Catalyzed and uncatalyzed reactions have identical mechanisms.
d.Rates increase with increasing concentration of reactants because there are more collisions between reactant molecules.
e.As a reaction proceeds at constant temperature, the rate of the reaction -[R]/t remains constant.

a.Reactions are faster at a higher temperature because activation energies are lower.	False, typically, Ea is considered constant under temperature ranges... Then, this is mainly because of more kinetic collisions
b.It is possible to change the rate constant by changing the temperature.	True, rate constant "k" changes according to K = -A*exp(-Ea/(RT)) chang ein T change K
c.Catalyzed and uncatalyzed reactions have identical mechanisms.	FALSE, catalyzed reactions have much more efficient reaction mechanism, therefore, rate is higher
d.Rates increase with increasing concentration of reactants because there are more collisions between reactant molecules.	True, more collissions, more favorable reactions
e.As a reaction proceeds at constant temperature, the rate of the reaction -[R]/t remains constant.	Depends on rate of reaction, if Zero order, this is true, otherwise false

Label each of the following statements as True or False 1) If no slack or surplus variable is needed to convert a primal constraint to an equation, the corresponding dual variable will necessarily be unrestricted. 2) If a surplus variable is used to convert a primal constraint to an equation, the corresponding dual variable will be unrestricted regardless of whether the primal is maximization or minimization. 3) The addition of a new activity can improve the objective value. 4) In...

For each statement below circle TRUE if the statement is true, otherwise circle FALSE. A hypothesis test uses data from a sample to assess a claim about a population. A randomization distribution will be centered at the value used in the null hypothesis. “Failing to reject the null hypothesis” and “accepting the null hypothesis” mean the same thing in a hypothesis test’s conclusion. The p-value is the probability, assuming the alternative hypothesis is true, of obtaining a sample statistic as...
