A student carries out four experiments to investigate the rate of reaction between 3.0 g of
calcium carbonate and hydrochloric acid.
$CaC{O_3}\left( s \right) + 2HCl\left( {aq} \right) \to CaC{l_2}\left( {aq} \right) + C{O_2}\left( g \right) + {H_2}O\left( l \right)$
experiment 1 $CaC{O_3}powder + 2.0mol\,d{m^{ - 3}}HCL\,at\,{35^ \circ }C$
experiment 2 $CaC{O_3}powder + 2.0mol\,d{m^{ - 3}}HCL\,at\,{35^ \circ }C$
