Design a circuit that will take two clocks with different pulses as an input, determine within one second the faster clock and lights an led to denote the faster clock. The led should stay on until it is reset by a control signal.
In the reaction below, 3.84 atm each of H2 and Cl2 were placed into a 1.00 L flask and allowed to react: H2(g) + Cl2(g) <=> 2 HCl(g) Given that Kc = 62.1, calculate the equilibrium pressure of HCl.
