The rate of the chemical reaction between substance A and B is found to follow the rate law. rate = \( k[A]^2[B] \), where k is the rate constant. The concentration of A is reduced to half of its original value. To make the reaction occur at 50% of its original rate, the concentration of B should be
The first step in producing pure lead from galena $(PbS)$ is as follows: $ 2{PbS}(s) + 3{O}_2(g) \longrightarrow 2{PbO}(s) + 2{SO}_2(g) $. All of the following are true concerning this reaction except:
Which of the following are true statements? I. The heat capacity of a substance is the amount of heat that substance can hold per unit of temperature. II. The specific heat for a single substance is the same for all phases of that substance. III. When heat is added to a fluid, its temperature will change less if it is allowed to expand.
Which species have delocalised electrons?
The following data was obtained for the reaction,
