See all →- For a certain reaction, the rate = k[A]^2[B], when the initial concentration of A is tripled keeping concentration of B constant, the initial rate would Answer: 4. increase by a factor of nine. Key idea: Rate is proportional to [A]² when B is constant. New rate = k(3[A])²[B] = 9k[A]²[B] , so... 1
- The decomposition of phosphine [obscured] on tungsten at low pressure is a [obscured] reaction. It is because the Answer: 4. rate is proportional to the surface coverage Key idea: on a metal surface at low pressure the surface is not saturated, so the ra... 1
