So you could measure the change in concentration per unit time to measure the rate of reaction at regular intervals. Or you could measure the increase in concentration of one of the products.

ZnCO3 + H2SO4---> ZnSO4 + CO2 +H2O
You put a capillary tube on top of a conical flask which leads into a beaker on water with a measuring cylinder upside down in water and collect the amount of CO2 per unit time. Then you draw a concentration against time graph and measure the half life to deduce the order of the reaction.

What are the disadvantages and advantages of biofuels?
Pros: can be carbon neutral which can reduce co2 emissions and global warming, some biofuels will work with existing tech.
Cons: many use crops/land that would otherwise be used for human consumption that will push prices up for food, costs money and energy to build the processing plants, new engines in some cases etc etc.
What are the disadvantages and advantages of biofuels?
advantages: - carbon neutral - biofuels are made out of living things which took in co2 whilst they were growing so when you burn them youre just releasing this co2 - cheaper than fossil fuels - renewable - plants can be planted again and again whereas fossil fuels eventually run out
disadvantages: - food shortages- using farmland to grow biofuels means less farmland to grow crops - produces lower energy
