Given the following reaction, sketch a reaction coordinate graph. The reaction involves two steps, step 1 is the slowest step and step 2 is the fastest step. Indicate on the diagram the overall enthalpy change of the reaction, the reaction for the transitions states and intermediate states.
H2(g) + 2ICl(g) –> 2HCl(g) + I2(g)
Examples of polyatomic ions Generally, polyatomic ions have suffixes that end in “ite” or “ate” if they contain oxygen atoms. chloride hypochlorite chlorite chlorate perchlorate Note: Chloride shown above is not a polyatomic ion, it’s a monoatomic ion consisting of only one atom. Examples of other polyatomic ions: Oxyanions Oxyanions are ions that contain […]
What are polyatomic ions? Ions are formed when neutral atoms gain or lose electrons. Similarly, a polyatomic ion is formed when a neutral molecule gains or loses electrons. A polyatomic ion is a charged group of atoms covalently bonded together. Majority of the polyatomic ions are anions, meaning they are negatively charged. Ammonium is the […]
