(ii) With reference to the three-step mechanism (Equations 3–5 ), and assuming that the second step (Equation 4) is rate-limiting, derive the chemical rate equation for this mechanism and then compare it with the experimental rate equation given in Equation 2. (iii)The activation energy for the forward reaction, Ef, of step 1 (Equation 3) is 243.4 kJ mol^-1. Given this information, determine the activation energy for the reverse reaction, Er, and comment on the significance of the value (one sentence only). You may often come across a question 'What gas turns limewater cloudy?' The answer to this question is well known. Carbon dioxide is the only gas that turns lime water cloudy. You may be wondering what is lime water used for. Limewater is an aqueous solution of slaked lime and you will find it in antacids, medicines and lotions. In this article, we have answered all the questions related to the reaction of lime water and.īut one of its most noteworthy property is that it is used to absorb carbon dioxide from the air. What happens when Lime Water reacts to Carbon Dioxide?Ĭarbon dioxide reacts with limewater to form calcium carbonate, which precipitates out of the solution. The carbon dioxide and limewater react to produce water in addition to the calcium carbonate.
