## Which of the aforementioned claims about dynamic equilibrium is untrue? At equilibrium, the system has undergone no net change. The concentration of the reactants and products are constant at equilibrium. The forward and backward reactions stop when the system is in equilibrium. The rates of the forward and backward reactions are equal when everything is in balance.

## Let's say I supply heat Q to a system. If it's internal energy increases by U and the work done on it is W then by the first law of thermodynamics, Q = U + W. Now, let's say that due to the thermal expansion, the gravitational potential energy of the system also increases by P. Would it be right to say Q = U + W + P? What if the kinetic energy also increases(by K), is it right to say Q = U + W + P + K

## In a constant pressure process, the change in internal energy is$U=\frac{3}{2}nRT=\frac{3}{2}P\left(V2-V1\right).$However in a constant volume, is the change in internal energy $U=\frac{3}{2}nRT=V\left(P2-P1\right)$ ?
