APFIVE Activation Energy in Synthesis Reactions
During a synthesis reaction experiment, a student combines elemental sodium (Na) and chlorine gas (Cl2) to form sodium chloride (NaCl). The student ensures that the reaction chamber is completely sealed and conducts the experiment at room temperature. After the reaction, the student notices that the yield of NaCl is significantly lower than expected. What conceptual mistake did the student make?
A
Incorrectly balanced the chemical equation
B
Failed to provide sufficient activation energy
C
Used an excess of chlorine gas
D
Conducted the reaction at too low a temperature
