Please could someone tell me if this is right?
A high clock speed allows the CPU to execute more instructions per second.
A low clock speed causes the CPU to execute less instructions per second.

yeah every instruction needs some number of clock cycles to execute (which you can look up in a manufacturers published data for the cpu chip)
so more clock cycles per second causes more instructions per second

For any particular CPU, yes.
If there are two different sorts, it depends on how many clock cycles are involved for each sort. Going back a few years, when Intel introduced the Pentium 4, it had roughly twice the clock speed of the Pentium III. It wasn't any faster, because P4 instructions took more clock cycles, but it looked great in marketing materials.
