An increase in the concentration of the reactants of a reaction leads to change in :

The rate constant for a first order reaction is 4.606 $$ \times $$ 10^-3 s^-1. The time required to reduce 2.0 g of the reactant to 0.2 g is :

If the rate constant for a first order reaction is k, the time (t) required for the completion of 99 % of the reaction is given by :

For the chemical reaction
N₂(g) + 3H₂(g) ⇌ 2NH₃(g)
the correct option is :
