Is this processor compatible with my laptop?

I want to upgrade my laptop with an Intel Pentium E5700 3 GHz Processor - Dual-core 800 MHz FSB. My laptop specs are: Dell Inspiron 1545 Pentium (R) Dual-Core CPU T4300 @ 2.1Ghz, RAM 4 GB, system type 64-bit operating system. Would this be compatable? Thank you :)
