Assertion :In any reaction, the rate of disappearance of a reactant is same as the rate of reaction. Reason: Both rate of reaction and rate of disappearance of a reactant represent decrease in the concentration of the reactant per unit time.

Write the expressions for rates of reactions in terms of concentration of reactants and products for the following reactions: i) 2(N)_(2) (O)_(s) harr2 (N)_(2) (O)_(4)+(O)_(2) ii) 2 (NO)_(2)+(F)_(2) harr2 (NO)_(2) (F)

Assertion :The rate of the reaction, A rarr B is the rate of change of concentration of a reactant or a product. Reason: Rate of reaction remains constant duringthe course of reaction.

The rate constant of a reaction depends on

Assertion : Order of a reaction with respect to any reactant can be zero, positive, negative or fractional. Reason: Rate of a reaction cannot decrease with increase in concentration of a reactant or a product.

For the elementary reaction M rarr N, the rate of disappearance of M increases by a factor of 8 upon doubling the concentration of M. The order of the reaction with respect to M is:

For a reaction 1/2 A rarr 2B rate of disappearance of A is related to the rate of appearance of B by the expression

In the following reaction, how is the rate of appearance of the underlined product related to the rate of disappearance of the underlined reactant: BrO_(3)^(-) (aq) + 5Br^(-) (aq) + 6H^(+)(aq) to 3Br_(2)(l) + 3H_(2)O(aq)
