Question
TRUE or FALSE? please explain each answer
a) For the reaction A 2B, the rate of the reaction is 2(d[B]/dt)
b) For the reaction A + B 2C, -d[B]/dt=-d[A]/dt=2d[C]/dt
c) For the reaction 2 A B, it is always true that -(1/2)(d[A]/dt)= [A]2
d) If a reaction is second order with respect to a particular reactant, doubling the concentration of that reactant doubles the rate of the reaction.
e) If the activation energy of a reaction is very small, the rate of the reaction will not be sensitive to the temperature at which it is carried out.
f) Reactions with very negative G values have lower activation energies.
Explanation / Answer
a) False , ( For the reaction A 2B, the rate of the reaction is 1/2(d[B]/dt) )
b) false , ( For the reaction A + B 2C, -d[B]/dt =-d[A]/dt = 1/2d[C]/dt )
c) false
d) false ( if concentration double , the rate of reaction will be four times higher)
e) false
f) true
