what is the ph of a 2.3 m solution of the weak acid h2s, with a ka of 1.19×10−7? the equilibrium expression is: h2s(aq) h2o(l)⇋h3o (aq) hs−(aq)

Asolution at 25 degrees celsius is 1.0 × 10–5 m h3o+. what is the concentration of oh– in this solution?

Reaction rate depends on how many molecules are coming into contact with each other with enough energy to react. increasing the temperature of the reactants will increase -
