Pregunta: For the reaction 2A→B, which is of second order with respect to A, the half life time is 1 hour. If the initial pressure of A is 1 bar, which will be the pressure of A, of B, and the total pressure after 1 hour, after 2 hours and when the reactions is finished?

After understanding the definition of half-life in a chemical reaction, apply this knowledge to the reaction given, knowing that half-life is the time it takes for half of the initial reactants to be consumed, thus after one hour, the pressure of reactant A will decrease by half due to the reaction.
