72. Solving a chemistry problem

53. Define the concept of the rate of a chemical reaction. Describe quantitatively (where possible) how external conditions (concentration, temperature, pressure) affect the reaction rate. Calculate how many times the reaction rate will change when the conditions indicated in the table (Table 5) change.
Reaction Temperature change Temperature coefficient Pressure change
53 H2 Cl2=2HCl - - 2 times increase
