Physical methods of finding the rate of reaction always involve:
Correct answer: B. A graph
- A. A catalyst
- B. A graph
- C. A calculating software
- D. None of These
Explanation
Option B is correct since the graph is the easiest method of finding the rate of a reaction given the concentrations. Option A is incorrect since a catalyst can only bring about a decrease in the activation energy and speed up a reaction. It cannot be used to measure the rate of reaction Option C is incorrect since calculating software would be a digital method and not physical. Option D is incorrect since it states none of these, which is not the case.

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
