Temperature dependent equation can be written as

For an endothermic reaction, where ∆H represents the enthalpy of the reaction in kJ/mol, the minimum value for the energy of activation will be

For a first order reaction, a plot of log (a – x) against time is a straight line with a negative slope equal to

Which one of the following equation is correct for the reaction:
N₂(g) + 2H₂(g) → 2NH₃(g)

For a chemical reaction 2X + Y → Z, the rate of appearance of Z is 0.05 molL^-1 per min. The rate of disappearance of X will be

The rate of a gaseous reaction is equal to k [A][B]. The volume of the reaction vessel containing these gases is suddenly reduced to one-fourth of the initial volume. The rate of the reaction would be

The rate law for a reaction between the substances A and B is given by Rate =k [A]ⁿ[B]ⁿ. On doubling the concentration of A and halving the concentration of B, the ratio of the new rate to the earlier rate of the reaction will be as
