Determine the direction of reaction if 1.00 M NOCl is combined with 0.500 M NO and 0.500 M Cl2 in a sealed flask. No reaction occurs. Reaction proceeds to the right toward the products. Reaction proceeds to the left toward the reactants. Reaction proceeds to the left toward the products.

It shows that the experiment is designed properly.

Answer:             1.0  × 10⁻⁵ msolution:                     as we know ph is given as,                                    ph  = -log [h⁺]and,                                    [h⁺]  =  10^-ph    (1)putting value of ph in eq. 1,                                    [h⁺]  =  10⁻⁵                                    [h⁺]  =  1.0  × 10⁻⁵ m
