What effect does temperature have on proton conductivity?

Higher temperatures decrease conductivity
Higher temperatures do not affect conductivity
Higher temperatures increase conductivity
Temperature has no effect on reactions

The correct answer is: Higher temperatures increase conductivity

As temperature increases, the kinetic energy of the protons within a substance also increases. This heightened energy facilitates more effective movement of protons, which enhances their ability to conduct electricity. In systems where proton conductivity is relevant, such as in electrolytes, higher temperatures can lead to a reduction in viscosity and greater ion mobility, contributing to improved conductivity. In contrast, lower temperatures can result in reduced molecular motion and increased viscosity, leading to decreased proton mobility and lower conductivity. Thus, it is clear that temperature plays a significant role in influencing proton conductivity, with higher temperatures positively correlating with increased conductivity.
