In which reaction, the reactants have less energy than the products ?

For a hypothetical reaction, the mean potential energies of reactants and products are 40 and 25 kcal per mol respectively. Calculate the activation energies of the forward and the reverse reactions if the threshold energy is 65 kcal. Also calculate the heat of the reaction.

A first order reaction is carried out with an initial concentration of 10 mole per litre and 80% of the reactant changes into the product. Now if the same - reaction is carried out with an initial concentration of 5 mol per litre the percentage of the reactant changing to the product is:

Fill in the blanks : For a reaction A rarr Product . The rate of the reaction doubles when the concentration of the reactant is doubled. The order of the reaction is ……….. .

A reversible chemical reaction having two reactant is in equiliberium. If the concentrations of the reactants are doubled then the equiliberium constant will :
