Pre-lab questions 1. what are four different factors that can influence the rate of reaction? 2. which of the factors you listed in question number one has the greatest influence on reaction rate? 3. when does the reaction between baking soda and an acid ingredient in bread dough begin?

Rate of reaction can be influenced by temperature, presence of catalyst, concentration of reactions and pressure.

Presence of catalyst has the greatest influence as it provides an alternate pathway of lower activation energy for the reaction to proceed. The reaction begins when they is sufficient energy needed for reaction. When the molecules collide in the correct orientation and with sufficient energy
