Initially, the rate increases until the reaction is at equilibrium. At equilibrium, the rate is constant.
As the reaction progresses, the rate decreases to zero when reactants are used up ( for irriversible reactions only )
Answer:
A) Glass
Explanation:
Glass is a conductor, so it allows heat to go through it (Ex. Touching a pie pan that came right out of the oven)
Rubber is an insulator, so heat has a hard time passing through (Ex. Using a rubber grip on a cast iron pan.
Cloth is also an insulator, so heat has a hard time passing through (Ex. Using a pot holder to prevent the counter from getting scarred)
Wood is also an insulator, so heat has a hard time passing through (Ex. Bedding for a rabbit hutch)
