T1 = 200K ; k = k1
T2 = 400K ; k = k2
= 2k1
Predict the rate law of
the following reaction based on the
data given below
2A + B → C + 3D
Assertion: rate of reaction doubles
when the concentration of the reactant is doubles if it is a first order
reaction.
For a first reaction, If
the concentration of reactant is doubled, then the rate of reaction also
doubled.
Rate constant is
independent of concentration and is a constant at a constant temperature,
no of moles of oxygen = (48/32) =
1.5 mol
∴
rate of formation of oxygen = 2 ×1.5
= 3 mol min-1
