In a coffee-cup calorimeter, 100.0 ml of 1.0 m NaOH and 100.0 ml of 1.0 H2SO4 are mixed. the initial temperature of each solution was 25.6 degrees Celsius. After the reaction the temperature of the solution was 31.3 degree Celsius. How much heat does the reaction generate?

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
