According to the collision model, why does increasing the temperature increase the rate of a reaction?
answer
Increasing the temperature increases the number of collisions that can occur with enough energy for the reaction to occur.
question
Use the graph to calculate the average rate of the reaction between 0 and 25 s.
answer
The average rate of reaction between two points = difference in concentration / time taken
Concentration of Br2 at 25 sec = 0.75 M (Approximately)
Thus, Average rate of reaction
= (1.00 - 0.75) / 25
= 0.25 / 25
= 0.01 L / mol..sec
question
H2+2ICl?I2+2HCl, rate=k[H2][ICl]
What is the overall reaction order?
answer
rate = k [H2] [ICl]
1. Overall reaction order = 1+1 = 2
question
What would happen to the rate if [H2] were doubled?
answer
The rate would double.
question
What would happen to the rate if [ICl] were doubled?
answer
The rate would double.
question
What is the reaction order with respect to A?
answer
2!
question
What is the reaction order with respect to B?
answer
0!
question
Given the data calculated in Parts A, B, C, and D, determine the initial rate for a reaction that starts with 0.55 M of reagent A and 0.90 M of reagents B and C?
