Answer to Question #67823 in Physical Chemistry for rahina

Question

Question 13 : The minimum additional energy, above the average internal energy, which the reacting molecules must possess so that their collision result in a reaction is known as
Thermodynamic energy
Activation energy
Kinetic energy
Threshold energy

Question 14 : The factor that affects the rate of reaction is
Catalyst
All of these
Temperature of the reactants
Nature and concentration of the reactants

Question 15 : In a reaction:
2
A
→
B
+
2
C
2A→B+2C
, which of the statement is true?
Rate of formation of B = Rate of disappearance of A
Rate of disappearance of A = Rate of formation of C
Rate of disappearance of A = Rate of formation of B
Rate of formation of C= Rate of formation of B
