Which outcome accelerates corrosion rate in galvanic cell with dissimilar metals in seawater when temperature increases?

💡 Explanation

When temperature increases in a galvanic cell reactions, ion diffusion rate increases in the electrolyte due to greater kinetic energy, intensifying electron transfer causing accelerated corrosion. Therefore, accelerated corrosion occurs due to increased ion diffusion, rather than embrittlement, oxide layer formation or reduced oxygen solutility effects.
