Mark all the true statements A.) The value of [R]/[P] is the equilibrium constant B.) The amount of P present will not change. C.) The concentration of [R] is constant. D.) The reaction P--> R no longer takes place
If the opposite signs attract each other in an atom and same signs pushes back each other. But in an atom if the electrons are attracted to proton(negative to positive) then why the protons in the center(nucleus) of an atom remain combined instead..
if 600 j of heat are added to 50 g of water initially at 20 degrees c.how much energy is this in calories?what is the
The k1 is on top of the right pointing arow and k2 is below the left pointing arrow and the arrows are like they are in equilibrium. The k3 is above the lone arrow in the second reaction. In the find expression part the N02 is a subscript of P
