rate equations

Question 1

What is meant by the term order of reaction with respect to a reactant

Answer 1

power of concentration term in rate equation

Question 2

how do change the value of k

Answer 2

by changing the temperature

Question 3

how can you determine a catalyst is present in a reaction

Answer 3

as it appears in the rate equation but not the overall equation

Question 4

for an order 1 reaction explain why doubling the temperature increases the rate alot greater than doubling concentration of a reactant

Answer 4

reaction occurs when particles have energy equal or greater than activation energy

doubling temperature gives many more molecules energy greater than or equal to activation energy

where as doubling only doubles the molecules with energy greater than or equal to activation energy

Question 5

what is the significance of a zero order reactant

Answer 5

it doesn’t appear in the rate determining step

Question 6

why are intial rates used to determine orders of reactants

Answer 6

as the concentrations of the reactants are known

Question 7

what is the relationship between the rate constant and temperature

Answer 7

it is exponential
