Gotta Go Fast!
The amount of time it takes for 50% of a sample to react.
What is half life?
The rate of the forward reaction is _____ to the reverse reaction.
What is equal to?
Le Chatelier's Principle only applies to reactions that are this.
What is reversible
The the first order half life equation
What is t1/2=0.693/K?
A K >1 tells us that which side of the reaction is favored?
What are products?
A(g)+B(g)↔C(g)
Increasing the pressure for this reaction will cause the reaction to shift this direction.
What is shift right? (toward less moles)
A reaction type where the activation energy graph has reactants lower than products along the y-axis.
What is an endothermic reaction?
You neglect x when K is less than this value.
What is 10-4?
4A(g)↔2B(g)+C(s)
Decreasing the volume will cause the reaction to shift in this direction
What is shift right
An exothermic reaction will tend to have a _______ K than an endothermic reaction as temperatures increase.
What is lower?
CaO(s)+O2(g)↔CaO3(s)
Increasing the temperature causes the overall pressure of the reaction drops. This reaction could be classified as.
What is endothermic
A reaction begins as a purple solution. Reactants are pink and the products are blue. As we increase the pressure, there was a noticeable color change to blue. Knowing this, the _____ has the least amount of moles in the reaction.
What are products
Step 1: Ag++Ce4+↔ Ag2++ Ce3+
Step 2: Tl++ Ag2+→ Tl2++Ag+
Step 3: Tl2++Ce4+→ Tl3++Ce3+
The overall reaction for this equation is this.
What is TI++2Ce4+→TI3++2Ce3+
Br2(g)↔2Br(g)
I increase pressure and the reaction turns red. I increase temperature and the solution turns clear.
a) Rxn is endothermic, Y=red
b) Rxn is exothermic, Y=red
c) Rxn is endothermic, X=red
d) Rxn is exothermic, X=red
What is C
A+heat→2B+C
In this combustion reaction, decreasing heat will cause the reaction to do this.
What is move slower in the forward direction, LCP doesn't apply, the reaction isn't reversible
