The standard Gibbs energy change at 300 K for the reaction 2A⇔B+C is 2494.2J. At a given time, the composition of the reaction mixture is [A]=21,[B]=2and[C]=21. The reaction proceeds in the :
If a piece of metal is heated to temperature θ and then allowed to cool in a room which is at temperature θ0 the graph between the temperature T of the metal and time t will be closest to :
Consider an ideal gas confined in an isolated closed chamber. As the gas undergoes an adiabatic expansion the average time of collision between molecules increases as Vq, where V is the volume of the gas. The value of q is :
