QUESTION 1 Variable(s) that affect rate include: temperature concentration pressure of gasses All of the above a and b only 1 points QUESTION 2 The rate constant (k) for a reaction: has units of M/s. changes with temperature is different for different concentrations of reactants All of the above b and c 1 points QUESTION 3 If a reactant is 2nd order, doubling the concentration of the reactant will: double the rate of the reaction triple the rate...
I need Number 3 answered and explained please. Briefly explain using appropriate formulas: How each of the following changes will affect the exchange rate (dollars per euro) according to the monetary approach to exchange rates 1. a. b. c. d. The US money supply increases The EU money supply decreases The US national income increases. The EU national income decreases. How each of the following changes will affect the real exchange rate (the number of US baskets per EU basket...
2. When using the method of initial rates to determine the reaction order of each individual reactant, why must data only be used in which one reactant is changing concentration but not the other reactants? 3. Briefly explain why the number of total drops being mixed in each experiment is kept constant throughout all five experiments. 4. Sketch a molecular‐level picture that illustrates why reaction rate increases when the concentration of a reactant is increased. Note – this might be...
1) What are the units on the rate constant ( the reaction is a 2nd order in one of the reactants and 0 in the other one) ? 2) What is the difference between reaction orders of the reactants and the stoichiometric coefficients of the reaction ? Do they have the same value? 3) Suppose we have a reaction of decomposition does the water affect the reaction rate? Assume we are not sure if the water is a reactant or...
1. which of the factors that affect chemical reaction rates explains why milk spoils slower when stored in the refrigerator? a. ctalyst b. temperature c. Concentration d. Surface area 2, The arte of a chemical increases with increasing concentrations of reactants because reactant molecules move faster when they are more concentrated a. True b. False
