Average Rate
What does "delta" stand for in kinetics and what does it look like?
Delta looks like a triangle and stands for final concentration minus initial concentration
What does the rate expression do differently to each concentration?
Divides them by the mole coefficient in the chemical equation
what is the symbol for the rate constant? Is it lower case or upper case? What is the formula for rate Law?
lower case k
rate=k[A]x[B]y[C]z
When is my office hours and what day is it on?
Mondays at 10:30
What is the formula for average rate? Needs to be 100% Accurate
(∆[A])/∆t
What is the difference between the rate of production and the rate of consumption? Which part of the chemical equation is used with these names?
The rate of consumption is the speed of the REACTANTS are consumed in the reaction
the rate of production is speed of the PRODUCTS being formed
Is there one unit for rate constant or is there a few? If so, how do you find it?
(Mn-1)/s
What are the 3 actors to play spiderman in live action?
Tom Holland
Tobey Maguire
Andrew Garfield
What is the sign of the average rate for reactants and for products and why are these the signs?
The sign for reactants are negative because reactants are being used up and for products are positive because they are being created
What is the balanced equation and rate expression for:
N2 + H2 --> NH3
N2 + 3H2 --> 2NH3
-1/1 * Δ[N2]/Δt =-1/3 * Δ[H2]/Δt = 1/2 * Δ[NH3]/Δt
What is the rate constant for the given equation? What units? rate=k[A]0[B]2[C]1
Rate = 300
A=5e-2
B=1.412e-7
C=9.21e-11
1.6e26 M2/s

The amount of hydrochloric acid in a system is initially 6 moles in 5ml of water. After this acid is reacted with sodium hydroxide, there is only 3 moles left in the same 5ml of water. This process took a total of 10 minutes. What is the average rate with SECONDS as the unit of time? Show your work
-1 M/s
What is the balanced equation and rate expression for the combustion of heptane?
C7H16 + 11O2 --> 8H2O + 7CO2
-1/1* Δ[C7H16]/Δt= -1/11 * Δ[O2]/Δt = 1/8 * Δ[H2O]/Δt= 1/7 * Δ[CO2]/Δt

What is Dr. Narayan's first name?

A gas grill was left on for 5 minutes. During this time, the combustion of propane gas occurs. What is the rate of formation of Carbon Dioxide if there was no product at the start and 0.49M of Carbon Dioxide remained after? What is the formula for this situation?
1.6e-3
C3H8 + 5O2 --> 4H2O + 3 CO2
H2O + O2 → H2O2
Balance the equation; the consumption of H2O is -1.35 M/s, what is the formation of hydrogen peroxide?
2H2O + O2 → 2H2O2
1.35M/s
For the following experiment, what would the rate be if the concentration of A was 0.5M and B was 0.14M. Use experiment 1 to solve for K.
4.9e-4M/s
When did the UTEP basketball team win the national championship?
