3. What is a catalyst? How does it work to affect reaction rates (list 2 ways)?
How does a positive catalyst generally affect a chemical reaction? A catalyst increases the temperature of the reaction which speeds the reaction rate. A catalyst reduces the frequency factor which speeds the reaction rate. A catalyst reduces the amount of solvent required which slows the reaction rate. A catalyst reduces activation energy which speeds the reaction rate.
A reaction that produces ammonia is shown below. How does the catalyst used in the industrial production of ammonia affect the reaction rates of the forward and reverse reactions? N2+3H2⇌2NH3 Select the correct answer below: 1. forward rate decreases, reverse rate increases 2. forward rate increases, reverse rate decreases 3. both the forward and reverse rates decrease 4. both the forward and reverse rates increase
List 3 factors that affect the reaction rates of enzyme catalyzed physiological reactions.
1.how does BAPNA affect reaction rates and explain why this effect makes sense 2.why do the reaction rates approach asymptote
please help me with this short answer portion i am confused 1. Explain why a catalyst must affect the rate of a reaction in both directions. 2. Calculate the concentration of a noncompetitive inhibitor (K yield 90% inhibition of an enzyme-catalyzed reaction. 2 x 10 M) need 3. For the operator (sin0/cos8)(d/de) and the eigenfunction sine, the eigenvalue a) sine b) 1 c) -sine d) -1 e) -cose 4. Evaluate numerically . Hint: use Euler formula. Show your work clearly...
Indicate what a catalyst does in a reaction to change the reaction rate, and provide a possible explanation for how Cu2+ acts as a catalyst in Kinetics of an Iodine Clock Reaction (non-reactive compounds KNO3 and (NH4)2SO4 are added to replace the reactants KI and (NH4)2S2O8) ). Hint: The Cu2+ ion, added in the form of a dilute Cu(NO3)2 solution, makes a suitable catalyst.
5. In what specific ways does globalization affect you in your daily life? (3 points) How has globalization changed interactions between buyers and sellers in the last few decades? (5 points) 6.
1a. How does a catalyst change the equilibrium of a reaction? r A catalyst lowers the activation energy and so changes the rate constants and therefore changes the equilibrium constant. A catalyst lowers the activation energy and so changes the rate constants and therefore changes the equilibrium constant. A catalyst helps to form more products so it always increases the equilibrium constant. A catalyst adds a reactant to the equilibrium expression and so changes the equilibrium constant. A catalyst doesn't...
What are bond ratings and why are they important? How does inflation affect interest rates? What is the term structure of interest rates?
How does social media affect the process of globalization? Give examples. In what ways does social media help in creating global communities? Discuss other positive influences of social media. What might be the adverse effects of excessive use of social media?
