Consider the reaction represented by the following equation: CuO\(_{(s)}\) + H\(_2\)SO\(_{4(aq)}\) → CuSO\(_{4(aq)}\) + H\(_2\)O\(_{(l)}\). Which of the following factors will not affect the rate of the reaction?
Particle size of CuO(s)
Concentration of H2SO4(aq)
Temperature of the reacting mixture
Pressure of reaction system
Explicació
The reaction rate between a solid and liquid will not be affected by pressure. Pressure majorly affects the reaction rate for gases.
