What are the coordination compounds that can be formed from Co 3+, NH3, CN-1 and K+ and which of these can exist as geometric isomers? Eg. of a compound formed: [Co(NH3)6](CN)3?
What is the value of the activation energy for a reaction if at 298K the rate constant is 10 s-1 and when measured at 308K the value increases to 25 s-1 (using Arrhenius Equation)?
If the rate of reaction doubles for every 10 °C rise in temperature, how much faster does
the reaction proceed at 45 °C than at 25 °C? At 95 °C than at 25 °C?
What is the limiting reagent when 0.50 mol of Cr and 1.0 mol of H3PO4 react according
to the following chemical equation?
2Cr + 2H3PO4 → 2CrPO4 + 3H2
If 0.20 mol of CrPO4 is recovered from the reaction described above, what is the percent yield?
