Assertion :The focal length of lens does not change, when red light is replaced by blue light. Reason: The focal length of lens does not depends on colour of light used.
Lithium sulphate does not form alums.
Li+ is too small to form a stable lattice required for double-salt/alum formation.
Assertion (A) Rate constant determined from Arrhenius equation are fairly accurate for simple as well as complex molecules.
Reason (R) Reactant molecules undergo chemical change irrespective of their orientation during collision.
(a) Both assertion and reason are correct and the reason is correct explanation of assertion (b) Both assertion and reason are correct, but reason does not explain assertion. (c) Assertion is correct, but reason is incorrect (d) Both assertion and reason are incorrect (e) Assertion is incorrect but reason is correct.
Assertion (A) Order of the reaction can be zero or fractional.
Reason (R) We cannot determine order from balanced chemical equation.
Assertion (A) Order and molecularity are same.
Reason (R) Order is determined experimentally and molecularity is the sum of the stoichimetric coeffcient of rate determining elementary step.
