10 Questions
What is the rate constant for a first-order reaction with a half-life of 200 seconds?
1.38 × 10^-3 s^-1
In a zero-order reaction, how does the rate change with an increase in concentration?
Rate is independent of concentration
What happens to the rate of a first-order reaction when the concentration of the reactant is doubled?
The rate is doubled
Which statement is true about the activation energy in a chemical reaction?
Activation energy determines the rate of a reaction
For a first-order reaction, how is the half-life affected by changes in temperature?
Half-life increases as temperature increases
What happens to the rate constant of a reaction if the temperature is increased by 10 degrees Celsius?
The rate constant doubles

First-order reaction
What does a negative value of the slope (m) represent in a graph of ln k against 1/T?
Decrease in the activation energy
What will be the effect on the rate constant when Ea is increased?
rate constant decreases exponentially
What will be the effect on rate if concentration is doubled in zero order kinetics?
Remains constant
